Open end type steel grating
Open steel grating means the steel grating with open ends.
The two sides of the steel grating with no frame.
The common size is 900mmx5800mm,900mmx6000mm.
Open steel grating is one of the most commonly used steel grating, also called metal open bar grating. Welded steel grating is made of carbon steel or stainless steel. Welded steel grating has anti-slip surface, corrosion resistance, good drainage function, high strength and load capacity. So it is widely used as walkway, stair, fence, shelf, ceiling and floor in many places.
* High strength and load capacity.
* Anti-slip surface.
* Corrosion resistance.
* Good drainage function.
* Easy to install and maintain.
