A galvanized steel plank is a construction tool used in industries such as construction, shipbuilding, petrochemicals, and power, and it belongs to the category of steel scaffolding boards. It is widely used for building work platforms, safety passages, scaffolding planks, and other scenarios.
Key Definition Points
Aliases: Steel plank, steel tread board, steel scaffolding board, hot-dip galvanized steel tread board, etc.
Material: Usually made of Q195 or Q235 carbon steel, treated with hot-dip galvanizing process, with a zinc layer thickness ≥80μm, providing excellent corrosion resistance.
Structural Features
Surface perforated for anti-slip (common hole size 12×18mm, hole spacing 30.5×40mm); some designs have triangular grooves or raised patterns to enhance compressive strength;
M18 bolt holes are usually provided on both sides for connection and fixation;
Sand-drain holes (diameter approximately 16mm) at the bottom to prevent sand accumulation;
Equipped with kickboards (height 180mm, coated with alternating black and yellow paint);
Folded edges with a bending angle of 90°±2°, with high flatness requirements of the board surface (deflection ≤5mm).
Standards: Comply with industry standards such as YBJ211-1988 and the latest T/ZLJYXH 2-2023, and must pass load tests including concentrated load 2kN or uniformly distributed load 6kN for 1 minute, with deflection ≤15mm/m.
Service Life: Under normal construction conditions, 6–8 years; after disposal, materials can be recycled with a recovery value of approximately 35%–40% of the initial investment.
