Anonymous users2024-02-07The selection of the cross-section of the steel structure member shall comply with the following provisions:
The rod should be of solid belly type or closed cross-section, and the end of the closed cross-section should be closed; When hot-dip galvanizing is carried out on the closed section, explosion-proof measures should be taken.
When the corrosivity grade is strong and medium, the T-section composed of double angle steel or the I-shaped section composed of double channel steel should not be used; When the corrosivity level is weak, it is not advisable to use the above-mentioned T-shaped or I-shaped cross-section.
When the rods of the section steel combination are used, the gap width between the sections should meet the requirements of the construction and maintenance of the protective layer.
The reason is that the steel structure is easy to find, and the steel structure is not too difficult to find. Regarding finding a specific steel structure anti-corrosion, I suggest you go here to see if the steel structure is anti-corrosion, the reason why the steel structure anti-corrosion here is relatively complete, the steel structure anti-corrosion network in other places may not be as comprehensive as the steel structure anti-corrosion here, to determine where you can find the steel structure anti-corrosion, the reason is that the steel structure anti-corrosion is easy to find, and the steel structure anti-corrosion is not too difficult to find now. Regarding finding a specific steel structure anti-corrosion, I suggest you go here to see if the steel structure is anti-corrosion, the reason why the steel structure anti-corrosion here is relatively complete, and the steel structure anti-corrosion network in other places, 4 3 3
The thickness of the steel structure member section shall comply with the following provisions:
The members of the steel plate combination shall not be less than 6mm.
Closed-section members, not less than 4mm.
The thickness of the angle steel section is not less than 5mm.

1) Overview:
ZH-E modified acrylic coating is a kind of high-grade coating with excellent comprehensive performance, which is widely used in automobiles, ships, machinery and equipment, metallurgy, chemical industry, electrical appliances, furniture, building interior and exterior walls, flooring, metal and non-metal internal and external anti-corrosion, with beautiful brightness and decorative properties, and also has durability, chemical resistance, water resistance, weather resistance, washing resistance, friction resistance, and superior anti-aging performance, acid, alkali, salt, chemical gas. It can replace the common polyurethane coatings and epoxy coatings in the current society.
2) Composition:
ZH-E modified acrylic paint is formulated according to the latest formula, and is made by synthetic reaction grinding of hadipocyanate, styrene resin, polyacrylate, polyester resin, chlorinated rubber, curing agent, leveling agent, defoamer, high-grade filler, etc.
3) Basic performance:
1. The paint film is plump, smooth and bright, beautiful and pleasing to the eye.
