Product Description:
Consisting of metal parts (screw, flat washers, nuts) and chemical tubes.
Metal parts are available in 5.8 grade steel, 8.8 grade steel, 304 (A2-70)/316 (A4-80) stainless steel and other materials.
Metal (except stainless steel) part of the surface treatment are:
1、Electro-galvanised (zinc layer thickness >5um), used in ordinary environment;
2、Hot dip galvanising (zinc layer thickness >50 um), used in corrosive environments;
The chemical agent consists of modified vinyl resin, quartz sand and curing agent.Product Applications:
Applied to non-cracked concrete, natural stone and other substrates, small spacing, small margins of the structural components of the fixed or equipment installation of high-strength chemical anchors in the high loads, vibration loads have a stable, excellent anchorage performance.Operation process:
1. Drill holes of appropriate diameter and depth using a straight hole drill bit
2. Use a dust blower to blow dust into the holes more than twice
3. Use the brush to clean the dust on the wall of the hole more than 2 times
4. Use the soot blower to blow dust into the hole until no dust overflows from the hole
5. Put in chemical anchor bolts
6. Use the torque drill to screw in the high strength chemical anchor bolt to complete the anchoring
