Precast Concrete Bolt Anchor M20 M10 M12 M36 Custom Steel Material

This bolt anchor series is designed specifically for precast concrete applications and comes in standard sizes such as M10, M12, M20, and M36. It provides reliable connections and lifting support for prefabricated concrete components such as slabs, beams, and walls during the construction process. For projects with special requirements, we offer customized solutions that can adjust bolt size, length, surface treatment, and load-bearing capacity to meet specific precast concrete component needs.

1. Securing M10/M12 bolt anchors for precast concrete wall panel installation in residential buildings
2. Using M20 steel bolt anchors to lift precast concrete beams in commercial construction projects
3. Fixing M36 heavy-duty bolt anchors for large precast concrete slabs in industrial plant construction
4. Applying customized bolt anchors for special-shaped precast concrete components (e.g., curved facade panels)
5. Installing steel bolt anchors to connect precast concrete columns with foundations in infrastructure projects

1. Q: What standard sizes are available for these steel bolt anchors?

   A: The standard thread diameter sizes are M10, M12, M20, and M36, which fit most common precast concrete component holes and meet basic construction needs.

2. Q: Why are these anchors suitable for precast concrete applications?

   A: They are made of durable steel (carbon or optional stainless steel) and comply with precast-specific standards (EN 13000). Their design ensures stable connection/lifting, even when used with precast concrete that meets the required strength (≥ C30).

3. Q: What aspects of the bolt anchor can be customized for special projects?

   A: Customizable aspects include size (thread diameter M8–M48, length 50mm–300mm), performance (load capacity up to 150kN, corrosion-resistant materials), and design (thread type, head shape like hexagon or round).

4. Q: How does the rated load capacity vary across the standard sizes?

   A: Load capacity increases with size: M10 (8kN–15kN), M12 (12kN–22kN), M20 (30kN–50kN), and M36 (80kN–120kN). The exact value depends on the anchor’s material and the precast concrete’s strength.

5. Q: What surface treatment options are available to prevent rust?

   A: Standard treatments include hot-dip galvanizing and zinc plating for dry construction sites. For customization, options like epoxy coating (for extra rust resistance) or passivation (for stainless steel) are offered.
