Steel Grate Stair Treads Introduction
Stair steel grid board also called stair step board.
Stair steel grid plate is made of steel grid plate processing
(steel grid plate is made of flat steel in accordance with a
certain distance and cross bar arrangement, and welded into the
middle with a square grid of steel products).
The surface of the product is generally treated with hot dip
galvanizing and electric galvanizing.
(1) According to the installation of the stair steel grid plate, it
is divided into the welded fixed ladder pedal and the bolt fixed
ladder pedal.
The welded and fixed ladder pedal is the steel grid plate, and the
bolted ladder pedal needs to add 65X5mm flat steel to the steel
grid plate as the side plate.
(2) according to the anti-skid requirements of the stair steel grid
plate, it can be divided into two kinds: the ladder pedal with
front guard plate (pattern plate or bar steel) and the ladder pedal
without front guard plate.
T325/30/100(For step width greater than 215mm but not greater than
305mm) For safety reasons, it is recommended that the customer use
the step with front guard.

Steel Grate Stair Treads Advantages
It has the characteristics of high strength and light structure:
because the product adopts the solid grid pressure welding
technology, it has the high bearing capacity, and is easy to
hoisting and so on;Beautiful appearance, durable;The standard
surface of steel grid plate is treated with hot dip zinc to make it
have good anticorrosion ability, and the surface is glossy and
beautiful.Good ventilation, lighting, heat dissipation,
explosion-proof and skid proof performance;Prevent accumulation of
dirt.
