GRC Post-Installation Fixing Methods Explained — Qinglong GRC Multiple Fixing System

GRC installation fixing methods include four types: chemical anchor fixing (pull-out resistance ≥3kN), welded connection (weld quality grade II), dedicated fixing bracket system (adjustment range ±20mm), and adhesive fixing (bond strength ≥0.5MPa). Qinglong GRC recommends the dry-hanging adjustable connection system, which features three-dimensional adjustment, is safe and reliable, and offers convenient installation.

Fixing verification: wind loads based on a 50-year return period; seismic actions based on the fortification intensity; dead loads with amplification factor considered; temperature stress calculated for the most unfavorable combination. After calculation, a super high-rise project adopted Qinglong GRC dedicated fixing brackets, which withstood typhoon tests with the fixing system remaining intact.

Chemical Anchor Fixing

Anchor pull-out resistance ≥3kN; anchorage depth ≥8d (d is the anchor diameter); thorough drilling and hole cleaning; accurate installation torque. Anchor fixing is safe and reliable.

Welded Connection Method

Weld seam length ≥60mm; weld leg size ≥4mm; weld quality grade II; proper rust-proofing treatment. Welded connection is firm and durable.

Dedicated Fixing Bracket System

Bracket thickness ≥4mm; adjustment range ±20mm; reliable anti-detachment design; durable anti-corrosion treatment. The bracket system offers convenient installation.

Adhesive Fixing Technology

Bonding area ≥40%; bonding thickness 3-5mm; proper substrate preparation; sufficient curing time. Adhesive fixing offers a clean appearance.

Firm fixing guarantees safety. Qinglong GRC offers multiple fixing methods to meet different needs.
