Chemical Anchor for Building

Shandong Weiran Building Materials Co., Ltd. is one of the leading manufacturers and suppliers of chemical anchor for building in China. If you're going to wholesale durable chemical anchor for building made in China, welcome to get pricelist from our factory. All customized products are with high quality and competitive price.

Chemical anchor for building is a new heavy-duty anchoring consumable free of expansion stress, assembled of high-strength metal stud, proprietary chemical capsule, nut, flat washer and spring washer. Different from mechanical expansion anchors which rely on extrusion fixation, it adopts special epoxy resin curing to bond the stud, cured resin and concrete borehole wall into an integrated high-strength composite, delivering anchoring performance equivalent to pre-embedded fixing parts. It is a national-standard preferred construction material for structural retrofitting, post-installed embedment and heavy equipment fixing.

• Zero expansion stress to avoid substrate cracking for wide compatibility: Chemical bonding generates no mechanical extrusion force after installation, preventing cracking of concrete, stone and brick substrates. It enables anchoring with small edge spacing, close anchor spacing and thin base members, ideal for beams, columns, balconies and narrow wall edges where conventional expansion anchors cannot be installed.
• Superior tensile load capacity far exceeding expansion anchors: Compact high-strength bonded layer after resin curing provides powerful encapsulation with excellent tensile and shear strength, bearing capacity greatly superior to same-size mechanical expansion anchors.
• Seismic and anti-fatigue performance for long-term stable service: Cured resin balances rigidity and flexibility with outstanding resistance to vibration, fatigue and creep, suitable for dynamic loads including equipment operation vibration, wind sway, thermal deformation and vehicle live load.
• Standard-compliant precision manufacturing for smooth project acceptance: Precisely machined qualified-hardness threads, scientifically proportioned resin with stable bonding strength; consistent batch performance without fake parameter labeling, fully complying with national construction anchoring codes.

• Structural renovation and reinforcement: Substitutes traditional pre-embedding for stable high-strength reinforcement in old building renewal and dilapidated structure retrofitting projects.
• Exterior curtain wall anchoring: Post-install fixation of keels for glass, stone and aluminum panel curtain walls plus external steel frames and canopy brackets; no wall cracking, adapts narrow-edge facade construction with neat appearance and reliable load capacity.
• Steel structure and equipment base fixing: Anchorage for steel columns, machinery bases, elevator footings and conveyor brackets; vibration-proof and anti-loosening for long-term heavy-load industrial workshop equipment installation.
• Commercial building construction: Fixing of workshop steel frames, ceiling trusses, pipe supports, fire protection fixtures and surveillance mounts with easy installation and sufficient load capacity for standardized bulk factory construction.
• Special difficult anchoring conditions: Ideal for close-edge installation, thin concrete, cracked concrete and stone masonry where standard expansion anchors fail to work, perfect for confined spaces, aged substrates and high-spec decoration projects.

Free of expansion stress and substrate cracking, these chemical anchors for building feature high tensile and shear strength as well as excellent seismic and corrosion resistance, delivering anchoring performance nearly equal to pre-embedded fasteners. They are the compliant preferred option for structural reinforcement, curtain wall, heavy-duty equipment and municipal engineering projects.
