تفاصيل المنتج

Duojia’s sleeve anchors for concrete leverage over 25 years of manufacturing prowess in our Yongnian District base, producing reliable internal expansion fasteners from premium 304 stainless steel. The plain surface finish enhances natural rust resistance, while the hex bolt allows straightforward wrench tightening for secure installations. Our 5,000+ square meter factory utilizes threading machines, cold pressing equipment, and welding robots to craft these anchors with precision, achieving a 500-ton monthly capacity. Installation is simple: drill a suitable hole in concrete or brick, clear debris, insert the anchor, position the fixture, and tighten the hex bolt to activate internal expansion for a tight hold—prevent overtightening to avoid substrate damage. Versatile for mounting machinery or furniture, they undergo grade inspections and come with dedicated after-sales support, including replacements within three weeks for any issues. Exported worldwide, these anchors embody Duojia’s commitment to innovative, eco-friendly fastening solutions.

Sleeve anchors for concrete are perfect for embedding in solid bases like walls or floors, commonly used in construction for attaching beams, railings, or electrical fixtures securely. Their 304 stainless steel resists rust in wet conditions, ideal for marine, bathroom, or exterior projects where exposure to moisture is high. In industrial settings, they mount heavy equipment or shelving to concrete surfaces, ensuring stability under stress. Duojia supplies these to markets in France, Australia, and Argentina, with easy installation: drill, insert, and tighten to expand internally for a flush, secure fit. They’re also valuable in furniture assembly and renovation, providing discreet yet powerful anchoring in brick or stone. This makes them essential for versatile, corrosion-free fastening in both professional and DIY scenarios across heavy and general industries.
