A steel grating is any regularly spaced collection of essentially identical, parallel, elongated elements. When two elongated elements are perpendicular, this is also known as a grid or a mesh. With over 20 years of experience and expertise, we offer the most complete types for customers. If the existing products fail to reach your requirements, we can design and manufacture steel gratings upon request.

1. Models of grating
The model usually includes three parts, the value of width multiplied thickness of bearing bar, spacing between bearing bars and spacing between cross bars, such as JG325/30/100 and JG255/30/100S.
The length of grating means the length of bearing bar while the width means the length of cross bar.
When the order is not big, the quantity is measured by piece. When the order is big, the amount is measured by area (m2) or weight (kg). (YB/T4001.1-2007 Standard)
4. Edge Welding
Usually, we use flat bar for welding the ends of grating. If demanded, we can choose different materials or no edge welding.
5. Surface Treatment
The architectural grating usually undergoes hot-dip galvanization. Other types of treatment or non-treatment are also available.
Beststeelgratings also manufactures grating clips for fixing steel bar gratings. It’s rigid and easy to dismount.
This clip is easy to install and competitively priced. However, for long-term usage and frequent vibration, the bolt will be loose.
Aside from easy installation and cheap price, this clip fastens two gratings together, which is very convenient. Like Type A clip, it will also go loose when long-term application and frequent vibration.
Because this clip is directly fixed on the bar, allowing for an excellent fastening effect, even under long-term usage and frequent vibration. The disadvantage is that users should weld the clip onto the bar when installing.
This clip provides strong and dependable fastening, even in a working environment with frequent vibration. Compared to other types of clips, this one is a little expensive but we believe it’s going to be used in more and more projects in the future for its excellent fixing and fastening ability.
For finished gratings, we usually pack them with steel belts and timbers, making it easy to load. As for steel gratings, we usually wrap them with flat steel. If you have special requirements, we can use packaging materials you appoint.
