Color-coated steel sheets are widely used in various fields due to their lightweight and high strength (tensile strength 280-550MPa),

Color-coated steel sheets are mainly used in industrial construction, animal husbandry, large public buildings, and metal manufacturing industries.

The thickness of color-coated steel sheets typically ranges from 0.2 mm to 1.5 mm, depending on the application and requirements.

High-strength bolts typically have strength grades of 8.8, 10.9, and 12.9, significantly higher than ordinary bolts.

Installation Steps for Pre-embedded Bolts

Ordinary pre-embedded bolts are sufficient.

Anchor bolts are indispensable fasteners in industrial and construction fields, primarily used to fix machinery, steel structures, etc.,

Corner braces are common structural members used to support members and plates.

Corner bracing should be designed as an axially compressed member.

After understanding the definition of purlins, let's discuss their specific functions.

According to relevant standards, carbon steel and alloy steel bolts are classified into more than 10 grades, including 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9

Bolts have many names, and people may use different terms.
