ISO Certified 304 Stainless Steel Chemical Anchor for Cracked Concrete M8-M30 Heavy Duty Fast-Curing with Cure Formula

説明

What Are Chemical Anchors?

Chemical anchors, also known as resin anchors, are high-performance fastening systems that consist of a steel rod or threaded bar bonded into a drilled hole using a synthetic adhesive cartridge . Unlike mechanical anchors that rely on friction, chemical anchors use a thermosetting resin to create a molecular bond between the metal element and the base material (concrete, masonry, or natural stone) . This provides superior load capacity and vibration resistance without creating expansion stress in the substrate .

Materials

• Resin Types: Polyester (styrene-free options), Vinyl Ester, Epoxy Acrylate, 100% Solids Epoxy

• Steel Components: Carbon Steel (Grade 5.8/8.8), Stainless Steel (A2/304, A4/316), Galvanized Steel, Deformed Rebar

Surface Treatment

• Resin Finish: Unfinished (chemical cartridge)

• Steel Finishes: Zinc Plated, Hot-Dip Galvanized (HDG), Geomet Coating, Plain (Oil-Coated)

Specifications

• Key Standards: ETA Option 1 (cracked concrete), ETA TR023 (post-installed rebar), LEED EQc4.1, A+ VOC emissions class

• Tensile Load Data (M16): Approx. 70.9 kN (destructive load)

Applications

• Structural steel column fixing and heavy machinery mounting

• Bridge parapets, highway barriers, and safety railings

• Curtain wall and facade anchoring systems

• Post-installed rebar connections in concrete

• Fixing heavy equipment in seismic zones (Category C1 rated)

• Overhead fixings and dynamic load applications

Best Practice Case Example

Scenario: Securing a primary structural steel column to a foundation in an industrial facility requiring seismic certification.

• Selected System: Two-part Styrene-Free Vinyl Ester Chemical Anchor (e.g., M16 application).

• Resin Type: High-performance vinyl ester with static mixer nozzle for correct ratio .

• Steel Component: M16 x 190mm threaded rod, Grade 8.8, zinc plated .

• Installation Data: 18mm diameter drill hole; 125mm embedment depth; cleaned per protocol (blow 3x, brush 3x); resin injected from bottom; rod inserted with slow rotation (approx. 300-750 rpm) until fully seated .

• Performance: Achieves destructive tensile load of approximately 70.9 kN in C25 concrete. System holds ETA Option 1 approval for cracked concrete and seismic Category C1 certification, ensuring structural integrity under dynamic conditions.
