Corrosion Resistant Customizable High Zinc Coating Steel Grating Platform Grating for Industrial Walkways

SURFACE PROCESS OF GRATING
HOT GALVANIZING
Normally,Hot galvanizing will be carried out after end welding process,For the thickness of bearing bars is not less than 5mm,the weight of average Zinc Layer will not be less than 610g/m2.When the thickness of bearing bars is less than 5mm,the weight of average Zinc Layer
Will not be less than 460g/m2. The quality and requirements after hot galvanizing are subject to the standards of GB/T 13912.

LACQUERING
To again protection layer through the ways of spraying,brushing and soaking.

SERVICE LIFE OF HOT GALVANIZING
Coated zinc thickness of 100um,the anticipated life of products in various circumstances.

ANTI-ACID AND ALKALI CORROSSION CAPACITY
The range of PH6 to PH12.5,a stable protective film will be formed on the zinc surface.it has good
anti-corrosive property.

CALCULATION OF WEIGHT AND AREA
1.The weight of gratings varies after end welded and hot galvanizing process. For normal industrial platform using 30mm pitch bearing bars,the weight will increase 12%;14% for 40mm pitch bearing bars and 16% for 60mm pitch bearing bars.
2.For those gratings processed according to the size supplied by customer,calculation will based on the actual area(including cutout and tap)
3.For those gratings processed according to customer's drawing,calculation will be based on the
total outside size(including cutout and tap)
4.For unusual size of grating cutouts shall not deduct from the length and width.

GNEE Steel Grating Application

Steel grating are designed and manufactured for various industrial and civil constructions in city road, gardens, yard, airport, railway and industrial engineering.

• Hot dip galvanized steel grating is the best choice for steel platforms in airports. Grating with 30 × 3 mm thick load bearing bars with a pitch of 30 mm and traverse bars at 50 mm or 100 mm is the suitable one.
• Steel grating, with robust design and spanning abilities, is very strong and safe for the support of floors and elevated walkway. It can be used for ceiling, interior decoration, platform aisle, ventilation windows, (Wells), advertising plaque and other construction.
• Widely used in the petrochemical industry, power plants, waterworks, sewage treatment plants, municipal works, sanitation projects in areas such as platforms, corridors, bridge, ditch cover, covers, ladders, fences, rails, and so on.
