Steel Grating

Hebei Yuanhang Traffic Facilities Co., Ltd. offers steel grating manufactured
by welding load-bearing flat bars and cross bars at fixed spacing to create an
integrated structure. Steel grating is a metal flooring product used for
industrial platforms, walkways, stair treads, drainage covers, and construction
applications. Available in carbon steel and stainless steel materials, it
includes plain, serrated, and I-bar types with various specifications for
different load requirements. Custom sizes and finishes are available for
industrial projects.
