Wedge Anchor China Factory Suppliers High Load Bearing Expansion Bolts
High-strength wedge anchors from a leading China factory. Our suppliers provide corrosion-resistant expansion bolts that lock firmly in concrete and brick for maximum load capacity.
The PDM Wedge Anchor is a professional-grade expansion bolt engineered for high-load bearing applications across residential, commercial, and industrial construction. Crafted from premium carbon steel (Q235/Q355) or high-grade stainless steel (304/316), these fasteners utilize precision forging and threading technology to ensure maximum tensile strength and a stable, vibration-resistant structure in various substrates.
Designed for versatility and ease of installation, our expansion bolts provide a secure mechanical bond in concrete, brick, and solid block materials. With available diameters from 4mm to 20mm and a corrosion-resistant galvanized or stainless finish, these anchors are the ideal choice for installing heavy-duty equipment, curtain walls, and industrial brackets where long-term security is non-negotiable.
