Q:Round and square steel which is strong
From the round and square steel specifications and appearance quality of the steel, 1. force large contact surface and relatively small pressure, 2. and three provide support force and the force behind. The force contact surface of round steel is very strong.
Q:What is the role of square toilet
Toilet partition top material: top surface affected by water vapor, the most susceptible to mildew, waterproof, heat-resistant material is better. The general use of colorful molding aluminum buckle and acrylic ceiling molding, the material surface resistance, and a thermal insulation material, is the ideal bathroom ceiling materials, specifications to 120mm wide strip and 300mm*300mm square, a flat surface structure and micro air two. Acrylic molding ceiling price is low, but easy to aging; colorful molding aluminum buckle higher prices, but the color diversity, durable, is the main use of modern bathroom ceiling. In addition, the use of aluminum plate or calcium silicate board, the latter surface coated with cement paint, low price, waterproof strong.
Q:Why is a point of penetration of 2 square steel welding
With 2.5 of the electrode try, I solder 1 will do, hand gestures as soon as possible, it is not so easy to point out the hole, if the conditions can choose carbon dioxide protection welding, but the cost of welding should be high
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:The steel and wood preservative in the flower is how to connect
Or with the aid of angle steel, angle steel and steel welding, wood preservative and angle connected by bolts.
Q:4*4 steel welding frame tank do strong?
If you want to be firm, you can use the three and four sections. The middle slot can be clamped on the edge of the fish tank, and the tripod should be four. It's so convenient and strong!
Q:How the steel columns and I-beam steel structure connection?
Steel structure engineering is mainly made of steel, and it is one of the main types of building structures.
Q:Building with steel or steel plate?
Recommended use of channel ten, three meters span is not large, there will be no vibration problems! Do not use the bearing structure of square steel tube, the solid steel with the specifications of the cost is too high and the bending strength is hollow, not recommended.
Q:The moment 2mm thick galvanized square steel tube using what welding methods
Let's use pressure welding! Gas welding and AC welder put the welding wear. Satisfactory adoption
Q:The steel structure material can do
Yes, both sizes can be done. The main check
STEXIN, an enterprise specializing in the production and sales of square bar, round bar and flat bar. The annual production capacity of square billet is 60,000 mtons, and sturtual steel 80,000 mtons.
