Heavy-Duty Shield Anchors | Concrete Expansion Rawl Bolts
Shield anchors are essential expansion fasteners widely used in construction and industrial fixing projects. Designed for solid mounting on concrete, brick, block and other masonry surfaces, these expansion rawl bolts deliver stable locking performance for both light and heavy-duty installation.
Manufactured from genuine Grade 4.8 and Grade 8.8 carbon steel, our shield anchors are zinc-plated or hot-dip galvanized for reliable rust resistance. The three‑segment shield structure expands evenly during bolt tightening, creating tight friction locking inside pre‑drilled holes. This simple but effective expansion mechanism ensures firm, vibration‑proof fixing for long‑term structural safety.
Suitable for permanent installation and temporary equipment mounting, these anchors are reusable and highly adaptable for various on‑site working conditions.

Real Customer Project Case – Australia Bulk Order
We regularly supply shield anchors for overseas construction and industrial clients. Recently, one of our long‑term Australian customers placed a formal bulk order for 1,000 sets of our M6‑M12 heavy‑duty shield anchors.
The customer is a local construction hardware supplier focusing on building renovation and masonry installation projects. They needed reliable concrete expansion anchors with stable expansion performance and good rust resistance to adapt to Australia’s changeable outdoor weather.
After confirming size specifications, surface finish and batch quality standards, we completed full material inspection, surface treatment testing and batch sorting before delivery. The full 1,000 sets of shield anchors were well packed and shipped smoothly, and the customer confirmed perfect fitting performance and consistent expansion effect after receiving the goods.
This bulk cooperation proves our shield anchors’ reliability for large‑scale engineering procurement and regular overseas wholesale orders. We keep stable stock of standard sizes to support fast delivery for global clients.
