GRC Product Quality Assurance System — Qinglong GRC Quality Control Explained

GRC product quality assurance relies on four mechanisms: raw material control (100% pass rate), production processes (process pass rate ≥98%), testing system (100% full inspection rate), and quality traceability (unique coding). Qinglong GRC is certified under the ISO9001 quality system and has established four levels of quality control—incoming material inspection, process control, finished product testing, and shipment verification—achieving a first-pass acceptance rate of ≥99% and a 100% strength compliance rate.

Safeguard measures: raw materials are inspected batch by batch, and non-conforming materials are never put into production; 36 process quality control points are monitored in real time; all finished products are tested with traceable data; quality records are established and kept for 10 years. In random sampling tests conducted by a testing institution, Qinglong GRC products showed an average flexural strength of 19.8MPa (standard requirement ≥18MPa) with a coefficient of variation of only 4.5%, far below the 15% standard requirement. Stable quality gives customers peace of mind.

Raw Material Control

Cement: strength grade ≥42.5, 100% pass rate; fibers: zirconia content ≥16.5%, alkali resistance up to standard; aggregates: continuous grading, mud content ≤0.5%; admixtures: good compatibility with cement. Quality raw materials are the foundation.

Production Process Control

Mix proportion accuracy: weighing error ≤0.5%; mixing process: 3-5min duration, uniformity ≥95%; forming control: compaction ≥98%; curing regime: temperature 20±2℃, humidity ≥90%. Process control ensures quality.

Comprehensive Testing System

Incoming inspection: every batch tested, non-conforming materials not put into production; process inspection: 36 quality control points; finished product testing: full inspection, only qualified products shipped; third-party sampling: twice a year, under continuous supervision. Strict testing as the gatekeeper.

Quality Traceability System

Unique codes: identity marking for every panel; production records: process parameters recorded throughout; testing data: all indicators fully preserved; usage tracking: project application status traceable. Full traceability with accountability assigned to individuals.

Quality is the lifeblood of an enterprise. Qinglong GRC treats quality as its life, earning customers' trust.
