 FAQ:

Q1: How soon can we receive the product after purchase?

A1: 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.

Q2: Can stainless steel rust?

A2: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:How to hollow square steel welding
Welding welding of thin-walled square steel, should be very careful when welding, arc welding technique should be used to pick, watch live pool, found that the weld pool collapsing must be timely arc.
Q:100*100*2.5 square with 20 square meters of housing security light steel structure:
The span of the main girder in the sunlight room is 20 square meters, but the different shapes lead to the different span of the main beam.
Q:The steel structure material can do
Yes, both sizes can be done. The main check
Q:The joiner board is fixed on the square on how
With self tapping screws, that is, with drill screws, building materials market can buy. Electric screwdriver, you can put the wood board through self tapping screws into the steel. But attention should be paid to buy the self tapping screw length, short patch does not live too long into the square, too much is not good.
Q:Hot dip galvanized steel can be welded
Hot galvanized square tubes can be welded.Hot galvanized pipe, welding needs to be polished galvanized layer, thoroughly remove zinc coating and oil, dust and other debris, exposing the tube itself metal color, and then welding.Zinc melting point of 419.53 degrees Celsius, low melting point, Zinc Oxide Zinc Oxide formed layer of hot combustion in high temperature welding thousands of degrees Celsius in the combustion of white smoke barrier zinc combustion, influence the flow of the weld pool of liquid metal, destruction of welding arc stiffness, the porosity, slag, weld crack.
Q:What is the role of square toilet
Toilet partition ground material: ground should use waterproof, dirty, anti-skid granite, etc., the height should be lower than other ground 10---20mm, floor drain should be less than 10mm, in order to facilitate drainage.
Q:Why is a point of penetration of 2 square steel welding
Electrode selection 2, 0J422, welding current about 80, if conditions permit, you can use carbon dioxide welding, welding process is very good grasp.
Q:What is the cold drawn steel material? Why did it break?
20 steel 45 steel Q235B a little more material, no annealing treatment
Q:4 x6 1.5 square meters thick, how much money
The steel prices generally calculated in tons. To see you say the steel is hot dip galvanized or black material. Hot galvanized general 4500/ tons, black wood generally in 3800/ tons. That is 4.5 yuan /kg and 3.8 yuan /kg. Forget it. You say this kind of steel is 2.355kg per meter. You can tell by your own price.
Q:How much is the thick wall hollow square 30*30
