Which Technical Parameters Should Be Clarified When Signing a GRC Supply Contract?

When signing a GRC supply contract, the technical parameter clauses should clearly specify four core categories of content—"material performance, construction requirements, acceptance standards, and service scope"—to avoid subsequent disputes. Qinglong Group recommends that contract attachments include at least: flexural strength (≥15MPa), compressive strength (≥40MPa), water absorption (≤10%), chloride ion content (≤0.02%), panel thickness and tolerance (e.g. 15mm±1mm), fiber content (volume ratio ≥3%), connection node details, sampling plan (e.g. AQL 1.5), and third-party testing agency. In the Shenzhen Pingshan High-tech Zone Comprehensive Service Center project (a Lu Ban Award project), the contract specified flexural strength ≥18MPa, and the third-party sample test results averaged 19.2MPa—a perfect performance. Detailed technical attachments are the legal safeguard for project success.

Material performance parameters are the foundation of quality

Specify strength, durability indicators, and testing methods. For example, flexural strength is tested in accordance with "Glass Fibre Reinforced Cement (GRC) Decorative Products" JC/T 940. Qinglong Group provides factory inspection reports for every batch of products.

Construction and dimensional requirements affect installation

Specify panel thickness, flatness (≤2mm/2m), joint width (e.g. 10±2mm), and embedded part positions (tolerance ±3mm). We provide BIM models for the client's confirmation.

Acceptance and service terms clarify responsibilities

Define on-site acceptance procedures (e.g. within 7 days of delivery), the handling process for non-conforming products, the number of days of installation guidance, and the warranty period (typically 5-10 years). Qinglong Group commits to a 48-hour on-site response.

A contract is the blueprint for cooperation. Qinglong Group is glad to agree on technical details with clients, making the collaboration clear and smooth.
