Step dimensions can be manufactured due to Customer requirements. Step grating may be made with different agreed mesh size and type of upper side (smooth or with anti-slip arrangement). Stair steps also can be manufactured with another size of bearing rod.

Any arrangements like cut outs in treading section are not recommended . Spacings between holes for fixing screws may be arranged according to Customer requirement. Stair steps can be supplied in wide variety of lengths.

Feature:

Appearance: simple lines. Silver exterior, modern trends.
Best drainage: leakage area of 83.3%, more than double the cast iron.
Hot-dip galvanizing: rust-proof and strong, maintenance and replacement.
Security design: box with hinged lid and connection, security, safe, easy to open.
Saving investment: large span. When overloaded, the lowest ratio of iron and saves replacement costs stolen, then crushed.
High strength: strength and toughness is much higher than cast iron, can be used for terminals, airports and other large span and heavy load environment.
Specifications and more: meet different environment and loading requirement. Span, the desired size and shape.
