Safety Hot Dip Galvanized Steel Grated Metal Stair Treads

T2 Welded Fixing Without Nosing Stair Tread For Steel Ladder 30mm Bearing Bars Pitch

Brief introduction of T2 flat steel 40mm spacing hot-dip galvanized steel grating steps

T2 type steel ladder step plate is made of load type flat steel and fried dough twist steel by manual welding. On the side side of T2, two bolts holes are used to fix holes on each side. The center distance of bolt holes varies according to the width of the treadle. When the width of the tread is 125, 155, 185, 215, 245, 275 or 305mm, the corresponding bolt hole center distance is 45, 75, 75, 100, 100, 100, 150mm, and the flat steel spacing is 40mm. The spacing of round steel is 10cm. The models of flat steel can adopt 25 * 3, 25 * 5, 32 * 5 and 40 * 5. The corresponding step plate length is 550, 900, 1300 and 1600mm. The T2 model is fixed with bolts, which will not damage the surface zinc layer and is convenient for installation and disassembly.

Performance and application scenario of T2 flat steel 40mm spacing hot-dip galvanized steel grating steps

The steel ladder step plate is installed with bolts, which is convenient for installation and disassembly, and has good bearing performance. The surface is hot-dip galvanized process, which can resist weak acid, weak alkali and oxygen oxidation and increase its service life. In addition, the shape design of the grid mesh makes it possible to avoid accumulation in rainy and snowy weather, avoid manual maintenance and save costs.

Error control of step steel grating plate with spacing of T2 40mm flat steel

According to the regulations, the allowable width error of steel ladder step plate is - 3mm to 3mm, the length constraint is 0-3mm, and the welding joint between front guard plate and edge and each loaded flat steel is fillet welding greater than or equal to 3mm.
