Galvanized steel grating is an ideal product for wet, slippery situation where corrosion resistance is vital. The mild steel gratings are hot dipped galvanized in the galvanizing bath. The galvanizing bath has got 7 tank surface cleaning process, the purity of the zinc used for hot dipped galvanizing shall be 99.95 % pure. The galvanized coating shall be as per IS-3202/IS–4759 / IS–2629/IS – 2633/IS–6745，ASTM –A -123 or equivalent to international standards. The appearance of surface is plain or serrated Galvanized steel grating is widely used in most general industrial plants as well as commercial buildings, it has wide applications as walkways, platforms, safety barriers, drainage covers and ventilation grates. It is also ideal for use as mezzanine decking since it supports the same loads as comparable solid flooring. More than that, its cost saving openness maximizes the circulation of air, light, heat, water and sound, while promoting cleanliness. alvanized Steel Grating Featu...

 Open steel floor grating, also know as welded steel bar grating, the most strong and durable metal grating products. They are made from the mild carbon steel or stainless steel. We provide a full solution of steel bar grating, press locked grating,heavy duty grating, steel stair treads,plank gratings,safety grating, trench cover,etc. All the gratings are extremely strong and durable for all the bearing application. And all grating products are fully recyclable. Due to the extremely strong and durable for all the bearing application,open steel floor grating has become the most popular grating in the markets.The stability makes them have a much higher performance in the application. We also can shear or form the steel gratings to any specification or desired shape.  Because of those excellent characteristic,the open steel floor grating can be widely used in flooring,deck,walkway,platform, decoration,etc. Open steel floor grating is widely used in flooring, catwalk, mezzanin...

Press-locked grating is also called pressure locked grating or press-locked steel bar grating. Basically, the press-locked grating have the same load capacity with the welded steel bar grating. The difference between press-locked grating and welded steel bar grating are joint connection technology and cross bars. Cross bars of welded steel bar grating are twisted square rods and the bearing bars are rectangular bars or I type bars. Both the bearing bars and cross bars of press-locked grating are rectangular bars. Compared to welded steel bar grating, which is produced through resistance-welding process, the press-locked grating is constructed with the two close-tolerance slotted bars bonded together by tremendous hydraulic pressure. This production can let press-locked grating be a permanent locking. Press-locked grating and swage-locked grating has excellent lateral stiffness, which can be used in some special applications. And the serrated surface is available for press-locked gr...

Serrated steel bar grating is very similar to the plain type, same process of production,only difference is made the bearing bar serrated before welding,but it increased the surface friction , the size and specs all the as plain bar grating . Serrated gratings are characterised by the increased friction coefficient. Bearing flat bars are serrated, which increases their anti-skid properties. They are used in making platforms in places exposed to snow, ice, grease and moisture. Technical data (loading, weight, mesh size, sizes of bearing flat bars) are the same as for the standard gratings of a flat bar and a bar. The gratings are made in various shapes according to the wish of the client. In case of installations in the open air and in plants with increased corrosion danger (e.g. chemical plants) it is recommended to enlarge the thickness of bearing flat bars by 1 mm. Dimensions recommended in order to avoid deformations caused by permanent loading. It is designed and engineere...

Steel bar grating has two surface type: serrated surface and smooth surface. Serrated steel grating is made of serrated steel bars, which can be low carbon steel bars, aluminum steel bars and stainless steel bars. The serrated steel bars are welded, press-locked, swage-locked or connected by rivets to form different types of steel grating. Compared to the plain steel grating, which is available for almost all of the applications, the serrated steel grating is widely used in the wet, slippy places, which need anti-slip performance. The serrated steel grating has various different types, according to the different fabrications and materials, the serrated steel grating can be divided into different types. The different types can be applied in different applications and supply more choice for customers.. Features of serrated steel grating Anti-slip. The raised surface supplies excellent slip resistance performance, which can be used in the wet and slippy places. Corrosion resistance....

Serrated Steel grating is made of high strength carbon steel, which has high strength for steel grate. Strength and toughness are much higher than that of cast iron. It can be used for large span and heavy load environment such as wharf, airport, etc. This product has a large net hole with the best drainage: the leakage area is up to 83.3%, which is more than two times that of the cast iron. Product appearance: concise lines, silvery appearance, modern ideas, material saving, saving investment: large span, heavy load, low price than iron; and can save iron because the stolencrushed replacement cost. Steel grating has two methods of welding and mounting style: plug welding and pressure welding. The processing is not very complicated but has high requirement for welding technology. Commonly we use fully automatic computer control welders to complete the welding process. For pressure welding process, the loading flat steel bar and crossing bar are arranged in certain distance in the lo...
