FAQ:

Q1: How do we guarantee the quality of our products?

A1: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q2: How soon can we receive the product after purchase?

A2: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

Q3: What makes stainless steel stainless?

A3: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q:Are galvanized flat steel and angle steel the same price?
No, generally speaking, galvanized flat steel is more expensive than angle iron
Q:The total floor distribution along the wall surface 40x4 galvanized flat steel, flat paint is painted yellow mark or brush a straight chute
Mainly to use insulating coatings.
Q:Please: hot galvanized flat steel and copper clad steel ground!
Compared with galvanized flat steel and other grounding materials, copper clad steel ground wire features: 1, corrosion resistance is better: no residual inside the bimetal, better corrosion resistance. The horizontal continuous casting process adopts high temperature melting, and the residue is calcined to overflow the copper surface, and can not be left in the copper clad steel conductor, so the corrosion phenomenon can not occur inside. 2 、 better electrical performance: the surface of oxygen free copper, good conductivity, the inner layer of high-quality carbon steel, skin effect principle, conductive, magnetic characteristics are excellent. The resistance is much lower than conventional materials such as steel, galvanized steel, etc. the surface layer is oxygen free copper.
Q:What about the installation height of the socket and the height of the ground flat steel?
In accordance with the final use of functional considerations, it is not recommended to reduce the socket installation height. According to the actual use of functional requirements, the socket location can be changed to optimize to avoid the ground flat iron position? If it is not feasible, then reduce the height of ground flat iron.
Q:Is the laying of a 40X4 flat steel for fire fighting metal trunking?
The angle between the bridge is connected or welded together by rivets, but in accordance with the relevant provisions of the State Grid, not admit that these are valid connection. At the same time in order to protect the ground, must have a grounding cable connection between all seams of metal objects, so that it can recognize all of its bridge is connected to one end, through one or a plurality of total grounding grounding.
Q:Lightning protection grounding, what is called three surface welding?
When lap welding is adopted, the welding length is as follows:1, galvanized steel bar is not less than its width of 2 times, three surface welding. When the width of flat steel is different, the length of lap should be wide. Before laying, the flat steel should be adjusted straight, simmer, bend not to die, straight line should not be obvious bending, and should stand upright.2, galvanized round steel welding length of 6 times its diameter, and should be double-sided welding (when the diameter is not the same, the length of overlap in diameter should prevail).3, galvanized round steel and galvanized flat steel connection, its length is round steel diameter of 6 times.4, galvanized flat steel and galvanized steel pipe welding, in order to connect reliable, in addition to contact in itBoth sides of the site shall be welded, and the flat steel itself shall be bent in an arc to be welded with the steel pipe.
Q:What is the difference between 60X6 and 50X4 flat steel in grounding?
The contact resistance varies with the return current.
Q:What is the weight calculation formula for galvanized flat steel and galvanized steel angles?
(1) grounding wire is generally made of 40mm * 4mm galvanized flat steel.(2) galvanized steel or angle steel for earthing body. The diameter of the steel pipe is 50mm, the wall thickness of the pipe is not less than 3.5mm, and the length is 2 to 3m. Angle iron shall be 50mm * 50mm * 5mm.(3) the top of the grounding body from the ground 0.5 ~ 0.8m, in order to avoid thawing soil, soil resistivity or steel angle as the root number of the ground around the body and decide, generally not less than two, each spacing is 3 ~ 5m(4) the distance between the grounding body and the building is over 1.5m, and the distance between the grounding rod and the independent lightning rod is greater than 3m.(5) the connection of grounding wire and earthing body shall be done by lap welding.
Q:What do the numbers in the steel HN346*174*6*9 refer to?
Large steel: large steel, I-beam, channel steel, angle steel and flat steel are hot rolled, round bar, Fang Gang, six angle iron in addition to hot rolling, there are forging, cold drawn and so on.
Q:8 what is the flat density?
8 mm flat steel density is about 7.85 g / cm.
