Q4: What makes stainless steel stainless?

A4: 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.

The awning material is usually divided into: "sunshine in canopy, canvas canopy, laminated glass awning, canopy tile".
Q:What is the hot dip galvanized steel, production process?
Also called hot galvanized and hot dip galvanizing: hot dip galvanizing is an effective way of metal corrosion, mainly used for metal structure on the facilities of the industry.
Q:The difference between square and square.
Square tube is kind of square body, many kinds of material can form a square body, most square to steel for the majority, after unpacking, smooth, curly, circular tube is formed by welding, pipe rolling into square tube and then cut into the desired length. Usually 50 bags each. Square pipe in the spot with large specifications in most, in the range of 10*10*0.8-1.5 to 500*500*10-25, square tube by use is divided into structural square tube, decorative square pipe, building square pipe, mechanical square tube, etc..Square tube is a square tube of a name, that is, the length of the same steel pipe. The strip is rolled by process.
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:How the steel columns and I-beam steel structure connection?
The square column is usually connected with a connecting plate, and the upper beam is arranged on the connecting plate and is fixed by an electric welding or a bolt.
Q:25-30mm drill pipe steel, to drill a lot, need what equipment
Square steel tube, large diameter thick walled square steel tube, square steel tube, seamless square steel low alloy square steel tube, 135*135*10 square steel tower with square steel tube, Q345B low alloy square steel pipe, seamless steel pipe 20# squareThe tube, as the name suggests, it is a square shaped tube type, many kinds of material material can form a square body, it is medium in, what, in what place, most square to steel for the majority, for the structure of the tube, decorative tube, square building.Square tube is a square tube of a name, that is, the length of the same steel pipe. The strip is rolled by process. Generally, the strip is disassembled, leveled, crimped and welded to form a round tube, then rolled from a tube into a square tube and cut to the required length. Usually 50 bags each.
Q:The difference between cold and hot galvanized steel hollow where
