Q355B Steel Structure Anchor Bolts 7 Type 9 Type HDG Foundation Bolts M6 M8 M10 M12 M16

These steel structure anchor bolts are used to fix steel columns, base plates, equipment foundations, embedded brackets, and structural components into concrete foundations. The 7 type and 9 type shapes are suitable for embedded anchoring where the bent or shaped end helps improve holding performance after concrete curing.

Q355B is a common structural steel material used in steel structure and construction applications. It is suitable for foundation anchoring, frame connection, support installation, and general structural fastening projects that require reliable mechanical performance. Carbon steel options provide practical strength and cost-effective bulk supply, while stainless steel can be selected for projects requiring different corrosion resistance or material requirements.

Surface Treatment Options

Zinc finish provides a clean surface appearance and practical rust protection for storage, transportation, and general construction use. It is suitable for steel structure anchor bolts used in indoor or controlled project environments.

Plain finish is suitable when the buyer requires an untreated surface, further processing, or project-specific coating after delivery. It can also be selected for embedded sections where the coating requirement is controlled by the project specification.

White zinc finish gives the anchor bolt a bright zinc plated surface, making it suitable for construction hardware channels and general fastening applications that need a clean appearance.

Yellow zinc finish can be selected for buyers who prefer a yellow passivated appearance or need different product identification in stock and project supply.

HDG, also known as hot dip galvanized finish, is suitable for outdoor foundations, exposed steel structures, humid environments, and infrastructure projects. HDG coating helps improve corrosion resistance and is often selected for anchor bolts used in long-term outdoor service.

Application

These Q355B steel structure anchor bolts are suitable for steel structure buildings, factory columns, warehouse frames, machinery bases, equipment foundations, bridge-related steel components, guardrail supports, solar mounting systems, pipe supports, construction brackets, and industrial installation projects.

For concrete embedding, the 7 type and 9 type anchor shapes help lock the bolt into the foundation after concrete curing. The exposed threaded section can then be used with nuts and washers to fasten base plates, support frames, and structural parts. This makes the product suitable for both standard construction supply and customized project production.

The product is suitable for steel structure contractors, construction companies, equipment manufacturers, infrastructure suppliers, fastener distributors, and project buyers who need anchor bolts in bulk with reliable material and coating options.
