A3: 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.

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.

Q:Round and square steel which is strong
Of course, the round steel is stronger. There was not because round steel is not convenient, a bar where rolling will affect the construction safety and progress. Log and wood with the same size and length to try to lift the increasing weight of the timber is certainly the first break. The cylinder is the strongest and most durable.
Q:The steel structure material can do
The square can be built steel shed, small steel shed are built with square, purlin is divided into 98% major plant two 4*6 and 4*8 5*10 are not a pillar or beam with the tube, because not standard
Q:Hot dip galvanized steel can be welded
Hot dip galvanized steel can be welded. The main methods of welding are as follows:1. manual arc welding. Remove the welding seam and the nearby zinc coating before welding. The welding rod can choose J421/J422/J423 and E5001/E5003 welding rod according to different requirements;2. gas metal arc welding. CO2 gas shielded welding can be used.3. argon arc welding.4. resistance welding.
Q:What is the role of square toilet
The steel is generally used in light steel structure mostly, such as steel roof, residential skeletonCommonly used structural steel according to the specifications of size for different purposes, decorative elements, assembled truss, supporting member, grid and other small pipe truss, large steel plant can be used for concrete filled steel tube truss steel column, a large stadium; another major use is round process pipeline, but in general the material and anticorrosion special requirements.
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:It can be used as the steel electrical equipment grounding
The steel can be used as grounding of electrical equipment, but because of the steel and the earth contact surface is relatively small, the grounding efficiency is not high, generally do not use. The steel pipe, angle steel and flat steel and other materials, the ratio of the circumference and area, has a larger contact area with the earth, in the same material case, get smaller grounding resistance, or in the same requirements of the grounding resistance, supplies are more economical than small, square steel.
Q:The steel structure of 40*80 steel, it is tempered glass top. The steel internal fight foaming agent. But there is rust in the inner surface. Will it affect the safety? How to deal with
Generally it is installed, both ends of the welding pipe will be closed, if the internal tube can be in a closed state, the inner wall surface after a certain period of time, will form a passivation layer, no further corrosion, so long as the section strength enough, in the period of use should be safe.
Q:You need to light steel keel wall square steel
Lightweight partition walls are usually made of lightweight bricks (aerated concrete or hollow bricks) made of cement mortar. The utility model has the advantages of good sound insulation and good fire prevention performance. (relative) but it is troublesome to thread the pipe in the wall. And wet operation, long duration.
Q:How to combine the paint and galvanized steel
No, as long as you choose the special galvanized steel pipe paint, mcGZ type is ok!
Q:How the two square welded T shape angle and turning angle, how to improve the speed and quality?
Also, I do not know whether you are welding stainless steel or iron, the novice can press the method to do, but ripe workers are visual, direct welding, of course, visual accuracy will always be a little worse,
