Steel grating stair treads are generally produced in what size it? Common treads size T1 to T4 30mm spacing 125,155,185,215,245,275,305 T1 to T2 40mm spacing 125,165,205,245,285,325 T3 to T4 40mm pitch 115, 155,195,235 , 275,315 T1 to T2 60mm spacing 185,245,305 T1 to T2 60mm spacing 155,215,275 from an economic point of view, it is recommended as far as possible modulus width (Series 1 using 125,155,185,215,245, 275, series 2 using 125,165,205,245,275mm etc.) multiple of the length of 100mm (e.g. 500,600,700,800,900,1000,1200mm etc.). Stair step size is based on the stairwell bay, depth, the height of the ladder where the pedal, each stair step to determine the height and width, length and width of the ladder and platform width settings. (Note: double stair treads stepping on each series is best to take an even number, so that the two ran stepping equal number of ladders pedal, also known as treads, non-slip treads, galvanized treads, etc. Depending on the installation, the general has. welding two types of fixed and bolted, welded directly to, without adding treads on the side of the keel, relatively economical and durable but easy to disassemble metal stair treads, treads on both sides of the fixed bolts need thicker plates, drilling on the side, the installation is directly bolted, reusable recycled stair treads with a new aesthetic, durable, quick installation, maintenance and so on; widely used in petroleum-slip pedal, pedal power ladders, chemical Factory ladders pedal, pedal steel ladder hydropower, cement ladders pedal, sewage treatment plants and other plants where the ladder pedal, pedal ladder, Asahi Connaught Anping wire mesh provided by Asahi Metal Mesh Products Co., Connaught.
