Scaffold Bill of Materials Estimator

Enter a run and a working height. The estimator resolves them into real V2 standards and H2 ledgers and returns a parts list you can price.

A planning indication only, for a plain rectangular run on level ground. Decking follows the standard SEIYON layout: one 500 mm plank per 1,829 × 1,900 mm opening across an H2-06 transverse ledger, or two 400 mm planks across an H2-09. Quantities cover standards, ledgers, planks, facade bracing and base jacks — guardrails, toe boards, wall ties, stairs and brackets are not included, and no load rating is implied. Coverage figures show the actual dimensions the resolved components reach, which round up to the nearest available member. Send us the project and our engineers will issue a full bill of materials and load analysis.
