Aluminum scaffold plank: check size before buying
Before you buy scaffolding boards or buy scaffold planks, record the scaffold model, clear width, support spacing and load. Send a supplier brief asking for compatibility and load/span evidence.
Build your plank buying brief
Enter your requirements to get review flags and a supplier brief. Example numbers are editable; site conditions start unconfirmed.
Your result will appear here after a check. Review flags and all inputs stay with the exported brief.
Procurement screening only. This result does not approve capacity, span, compatibility, erection or use. A competent person must verify the exact model, assembly, concentrated loads and local requirements.
Method, sources and limits · reviewed 14 October 2026
Jurisdiction-specific width checks and site risk flags support purchasing questions. AU duty bands apply to general scaffold planning; timber and aluminium spans always need product/design evidence. Unknown information remains open. RFQ-ready means a brief can be sent, not that a plank is approved.
Read the detailed evidence and procurement reportCompare scaffold plank quotations on the same basis
Send the exported brief with quantity, delivery destination and required date. Ask each supplier to identify the quoted model and state what is included. Price, stock, minimum order and lead time require confirmation for your order.
Fit
Model drawing, overall dimensions, bearing points, hook/lock geometry and written compatibility for the existing system.
Rating
Model-specific load/span table, loading pattern, permitted support arrangement and relevant test or conformity documents.
Delivered cost
Unit price and currency, quantity, accessories, packing dimensions, gross shipping weight, freight, taxes and unloading arrangements.
If quote A includes locking hardware and freight while quote B excludes them, ask for matching line items before comparing totals. Reject an undocumented substitution even when its nominal length and price look attractive.
Scaffold boards, aluminium planks and framed platforms can have different supports and locks. Confirm the component type from a drawing; a familiar product name does not establish interchangeability.
Aluminium scaffold plank dimensions: measure the support, not just the board
Use these checks for a new platform or replacement. Include a marked drawing and photographs where the existing part has no readable model label.
Scroll the table sideways to compare all three columns.
| Check | Record | Purchase decision |
|---|---|---|
| Single-plank width and profile depth | Width of one component and its full section height, both in mm. | Record separately from assembled platform width and extrusion wall thickness. Neither proves a load rating. |
| Overall length | End-to-end plank dimension, including any projecting hooks. | A listed 3 m length is not evidence of an allowable 3 m unsupported span. |
| Support spacing | Distance between the actual bearing/support locations. | Request the model load/span table and permitted support and overhang arrangement. |
| Clear platform width | Usable width of the assembled working platform. | Do not enter the width of a single narrow plank when several form the platform. |
| Hooks, locks and bearing | Profile, opening, engagement and anti-lift mechanism. | Match a drawing or identified replacement part; similar dimensions do not prove compatibility. |
| Load and load pattern | People, tools, materials and concentrated loads. | Confirm both the deck and complete scaffold rating; kg per bay, lb/ft² and kN/m² describe different quantities. |
Published model sizes: reference examples, not universal dimensions
Specify the model first, separate overall length from support spacing, and distinguish one plank’s width from the assembled platform width. There is no verified universal aluminium size or thickness-to-duty conversion in the evidence used here. These two framed platforms illustrate catalogue sizes; they are not a stock claim or a substitution recommendation.
7 ft × 19 in
Nominal size converted: 2,133.6 × 482.6 mm.
Not established by the headline size: exact hook-to-hook length, profile depth, bearing locations and tolerances. Request the drawing.
10 ft × 19 in
Nominal size converted: 3,048 × 482.6 mm.
Not established by the headline size: exact hook-to-hook length, profile depth, bearing locations and tolerances. Request the drawing.
Manufacturer listings checked 21 October 2026. Unit conversion: 1 in = 25.4 mm; 1 ft = 304.8 mm. Converted nominal dimensions are not measured manufacturing dimensions.
Deflection limits
OSHA 1926.451(f)(16) requires that platforms do not deflect more than 1/60th of the span when loaded. Arithmetic examples: a 3,000 mm span gives 3,000 ÷ 60 = 50 mm; a 10 ft span is 3,048 mm and gives 50.8 mm (2 in). These spans are different. This limit does not calculate capacity, approve a span or authorize a site load test. Ask for the model’s load/span evidence and specified support arrangement.
Certification boundary
The public preface to AS/NZS 1577:2018 says working load limits may be designed by theoretical analysis as an alternative to design by testing. It does not provide the full requirements or certify any model. Request the applicable design and test evidence from the supplier; matching external dimensions does not establish conformity.
Before ordering: Confirm bearing engagement and permitted overhang for the actual system. Some overhang may be part of an approved arrangement; a longer plank is not automatically unsafe or suitable. Missing dimensions can lead to incompatible locks, return freight and replacement delays. Send a marked drawing and get written compatibility confirmation before accepting a substitute.
Dimension evidence reviewed 21 October 2026. The standards preview is partial; clause-level compliance remains to be confirmed for the supplied model.
Comparing scaffold board materials: Aluminium vs Timber vs Steel
Material alone does not establish a plank’s service life, capacity or total cost. Compare the same component type, dimensions, support arrangement and intended loading, then use model-specific documents and inspection criteria to make the purchase decision.
| Feature | Aluminium Planks | Timber Boards (e.g. LVL, Solid) | Steel Planks |
|---|---|---|---|
| Service life & total cost | No universal service-life or resale figure. Check the exact model warranty, inspection criteria, repair policy and delivered replacement cost. | No universal service-life or resale figure. Include grading, condition checks, storage, repair policy and replacement cost. | No universal service-life or resale figure. Check the exact model’s corrosion protection, inspection criteria and replacement cost. |
| Condition checks | For metal planks, check welds, rivets, end caps and bent or crushed sections against the manufacturer’s criteria. | Check for damage, cuts, splits, damaged end bands, warping, excessive wear and rot. | For metal planks, check welds, rivets, end caps, deformation and corrosion against the manufacturer’s criteria. |
| Weight & handling | Use the declared weight for the complete model and assess handling for its length and work conditions. | Use the grade and declared weight for the actual board; also assess condition and handling at the site. | Use the declared weight for the complete model and assess handling for its length and work conditions. |
| Evidence to request | Exact model load/span evidence, support details, compatibility approval and the applicable local standard. | Board grade/identification, condition and a matching span table for the actual support arrangement. | Exact model load/span evidence, corrosion protection, compatibility approval and the applicable local standard. |
Plank condition checks vary by material
WorkSafe Victoria’s 2024 industry standard lists defects that require timber planks to be removed from use, including damage, splits, damaged end bands, excessive wear and rot. For metal planks it identifies cracked welds, missing rivets or end caps, bent or crushed sections, and heavy rust or corrosion. Follow the applicable local requirements and the product manufacturer’s inspection instructions. WorkSafe Victoria: Scaffolding industry standard (2024), scaffold plank inspection
When to Choose Aluminium
Choose a material only after confirming the scaffold system accepts that exact platform. Compare model-specific capacity, span, weight, connection details, maintenance instructions and delivered cost. A replacement aluminium plank still needs matching hooks and locks plus written compatibility evidence.

Email an RFQ for this model and quantityHow the checker uses guidance and where it stops
The checker compares your entries with selected planning thresholds and flags missing information. It does not calculate structural strength, certify a product or replace a scaffold design. Unknown conditions stay under review; near power lines, soft ground and proposed occupied movement require a site-specific assessment.
Australia: general scaffold planning
The general guide describes light duty up to 225 kg per platform per bay, medium up to 450 kg and heavy up to 675 kg. Associated platform widths are approximately 450 mm, 900 mm and at least 1,000 mm; concentrated loads are 120, 150 and 200 kg respectively.
These are planning references for the complete platform, not ratings for an individual plank. Special duty, tower design, local rules and manufacturer instructions need separate confirmation.
Safe Work Australia: General guide, p. 13 (July 2014)United States: OSHA span and overhang rules
The general platform-width rule is 18 in (457.2 mm), with defined exceptions. Above 10 ft, fall protection depends on scaffold type. Check safe access when the platform is more than 2 ft above or below its access point.
Schematic, not to scale. CL = support centerline. The 6 in minimum applies to unrestrained ends; hooks, cleats or equivalent restraint change this requirement. See the maximum overhang limits and exceptions below.
Overhang boundaries: OSHA 1926.451(b)(4) and (5) require an unrestrained platform end to extend at least 6 inches (15 cm) over the support centerline. The default maximum is 12 inches (30 cm) for platforms 10 ft or shorter and 18 inches (46 cm) for platforms over 10 ft. Greater overhang is allowed when the cantilever is designed and installed to support the applicable load without tipping, or guardrails block access to its end. Confirm the applicable rule and exact model arrangement.
OSHA requires inspection for visible defects before each shift. Electrical distances depend on insulation and voltage: 3 ft minimum applies only to insulated lines below 300 V.
OSHA 1926.451: platform, access and inspection requirementsUnited Kingdom: task and configuration
HSE says working platforms should be fully boarded and wide enough for work and access, usually at least 600 mm. Check support and overhang against the specific board and configuration.
A narrower entry triggers review, not an automatic conclusion that every narrow proprietary platform is prohibited. Use the manufacturer instructions and competent design review for the actual system.
HSE: scaffolding informationEurope: EN 12811-1 Load Classes
BS EN 12811-1 sets performance and design requirements for access and working scaffolds. Its loading classes describe scaffold working-area loads; they do not give a standalone plank a universal rating. Confirm the selected duty class and the supplied system’s design with the manufacturer and a competent designer.
| Load Class | Uniformly Distributed Load (UDL) |
|---|---|
| 1 | 0.75 kN/m² |
| 2 | 1.50 kN/m² |
| 3 | 2.00 kN/m² |
| 4 | 3.00 kN/m² |
| 5 | 4.50 kN/m² |
| 6 | 6.00 kN/m² |
These values describe uniformly distributed loads for scaffold duty classes, using the UDL column in HSA’s Table A1. The full table also covers concentrated and partial-area loads; class 1 platform units must support class 2 service loads even though the complete scaffold has a lower class 1 rating. The UDL column alone cannot establish an individual plank’s capacity or assembly suitability. Request the full model-specific loading and design evidence.

Worked examples: what to send and what to hold
These examples demonstrate the checker, not completed customer projects. Reproduce them by entering the values and conditions in the tool.
300 kg request with a 600 mm platform in Australia
Enter Australia, aluminium plank, 300 kg per bay, 600 mm clear width, 1,800 mm support spacing and 3,000 mm height. Select firm level ground, stationary use, checked overhead clearance and confirmed inspection records.
The result requires manual review because 300 kg falls within the medium-duty planning band and 600 mm is below its 900 mm width reference. Request a suitable system configuration; increasing the entered width alone does not prove that the existing scaffold is adequate.
Two reference platforms for a freight enquiry
Select M-MPA1019 and quantity 2 in the weight calculator. The published 42.46 lb per unit gives 84.92 lb / 38.52 kg for the products.
The calculation uses lb × 0.45359237 and rounds at display. Ask for packed dimensions and gross shipping weight separately. This arithmetic does not establish capacity, compatibility or the carrier’s chargeable weight.
Hold the order for clarification if identification, load/span evidence, locking compatibility or an inspection responsibility is missing. Keep flagged conditions in the exported brief so the supplier can answer them explicitly.
Questions before buying scaffold planks
What should I check before I buy scaffolding boards?
Confirm whether the order is for loose boards or a framed platform, and which materials and models your scaffold manufacturer permits. For a replacement, identify the existing scaffold make/model and photograph the bearing, hook and locking details. Use the checker to record clear platform width, support spacing, intended load and site conditions, then add overall board dimensions, quantity, delivery destination and required date to the brief. Ask the supplier for written compatibility, model-specific load/span evidence and an itemised delivered quote. Price, stock and lead time remain unconfirmed until the supplier replies.
What should I check before I buy scaffold planks?
First identify whether you need loose scaffold planks or a framed platform. Record the scaffold make and model, clear platform width, support spacing, intended load including point loads, quantity, delivery destination and required date. The checker screens load, width, span and site conditions; use the dimension checklist below for plank length, profile and hook/lock details. Ask for model-specific compatibility and load/span evidence, price, stock and lead time. Do not substitute a generic duty label for a manufacturer rating.
How much do scaffold boards cost, and can I order one replacement?
Price and minimum order quantity need a supplier quote for the exact material, profile, length, connection and quantity. Include delivery postcode or port, required date, currency, packing and unloading needs. Ask the supplier to separate product price, freight, taxes and any applicable import charges. One replacement still needs positive system identification; this page does not confirm stock or a universal unit price.
Are aluminium scaffold planks, boards and framed platforms interchangeable?
These names overlap in buying enquiries, but the components can differ in supports, hooks, locks and loading. Aluminium and aluminum are regional spellings of the same material. Match the actual manufacturer, model, drawing and approved scaffold configuration before substituting any board, plank or platform.
How do I choose aluminium scaffold plank dimensions?
Record overall length, single-plank width, profile depth, actual support spacing, clear assembled platform width and connection geometry separately. The checker collects clear width and support spacing, but it does not collect plank length, profile or hook/lock dimensions. Add those measurements and any drawing reference to your supplier enquiry; leave unknowns for the supplier to confirm. Obtain a load/span table for the exact model and loading pattern; neither overall length nor a general duty class establishes a safe span.
Is there one standard aluminium scaffold plank size?
Use an identified model, not a universal size assumption. The linked Metaltech examples are catalogued as 7 ft × 19 in and 10 ft × 19 in. Those nominal sizes do not establish exact overall length including hooks, manufacturing tolerances, bearing locations or cross-brand compatibility. Request a dimensioned drawing before ordering a replacement.
Can plank thickness or a deflection calculation prove capacity?
No. External profile depth is not wall thickness, and neither provides a load rating by itself. The OSHA span/60 calculation describes a deflection limit, not a capacity calculation or permission to load-test equipment yourself. Obtain model-specific design evidence and instructions for the actual supports, loading and scaffold system.
How much does an aluminum scaffold plank weigh?
Weight depends on the complete model, not just material density. The reference calculator uses Metaltech M-MPA719 at 27.5 lb and M-MPA1019 at 42.46 lb, with links to the manufacturer. These are example products, not a stock claim. Add packaging, pallets and accessories when requesting shipping weight.
Should I buy aluminium, steel or timber scaffold planks?
Start with the materials and models permitted by the scaffold manufacturer. Do not assume a service life, purchase price, handling advantage or load rating from the material name alone. Compare the exact model’s declared weight, permitted support arrangement, load/span evidence, warranty, inspection criteria and replacement cost for your expected use. WorkSafe Victoria lists visible rejection criteria for both timber and metal planks; the applicable local rules and manufacturer instructions still govern.
Can I buy used scaffold boards safely?
Ask for traceable identification, service history, condition photographs and inspection records. Missing labels, cracks, damaged hooks or locks, corrosion, distortion and undocumented repairs need competent review. Do not accept a seller’s generic compliance claim in place of model documentation and an inspection of the actual equipment.
Does an RFQ-ready result approve the plank for use?
No. RFQ-ready means the entered brief has no unresolved screening flags. The checker does not calculate structural capacity or approve a span. Manufacturer documentation, local requirements and competent site review remain necessary before ordering or use. Keep every flagged issue in the supplier enquiry.
