Product Description
Outdoor residential building metal stair treads welded Galvanized steps steel grating
Introduction of Steel grating:
There’re three kinds of steel gratings, plain style grating, serrated steel grating and I bar steel grating. They are widely used in steel structure platform, stair tread, sidewalk, drainage and well cover, etc. We are professional factory to design and manufacture standard steel grating and customize according to client's requirements.
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.
Description:
(1) Structure: Welding with flat steel and cross/round bars with certain distances.
(2) Features: High strength, light structure, high bearing.
(3) Surface: The hot dipped zinc coating gives the product excellent anti-corrosion.
