Application Scenarios
Steel grid board has been widely applied in both domestic and international industries, primarily used as:
Industrial platforms and ladder pedals
Handrails and channel floors
Railway bridge side roads and high tower frame platforms
Drain covers and well covers
Road crossing gates and stereo parking facilities
School, factory, and enterprise applications
Playground and garden villa fencing
Residential exterior windows and balcony guardrails
Highway and railway guardrails
Steel grating is manufactured using world-class equipment that arranges bearing bars and cross bars in longitude and latitude order at specific distances. Cross bars are pressed into bearing bars using high-tension resistance welding controlled by computer systems, producing high-quality gratings with firm welding, smooth surfaces, and high strength.
Frequently Asked Questions
What are bearing bars and cross bars?
Bearing bars carry the load; cross bars hold the bearing bars in place.
Can steel grating support heavy machinery?
Yes, with proper design, steel grating can support industrial equipment.
How is steel grating installed?
It can be mounted on support frames, welded, bolted, or anchored depending on the structure.
Can steel grating be cut on-site?
Yes, using cutting tools suitable for steel, such as angle grinders or plasma cutters.
What is the difference between welded and pressed steel grating?
Welded grating has bearing and cross bars welded; pressed grating uses pressure-locked joints.
Is maintenance required for steel grating?
Minimal maintenance is needed; periodic cleaning and inspection are recommended.
Can steel grating resist chemicals?
Stainless steel or coated grating offers resistance to many chemicals.
