Which Clauses Must Be Clearly Defined When Signing a GRC Procurement Contract?

In the procurement of architectural decoration materials, GRC (Glass Fiber Reinforced Concrete) is a key material combining artistry and functionality, and the clarity of its procurement contract terms directly affects project quality and cost control. Qinglong Group, with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, draws on practical cases from thousands of projects to outline the core clauses that must be clarified when signing GRC procurement contracts, helping developers, designers, and contractors avoid risks and achieve win-win cooperation.

1. Material Performance Indicators: Building a Solid Foundation for GRC Quality

The contract must specify the core technical parameters of GRC materials, including flexural strength (recommended not less than 15MPa), bulk density (typically controlled at 1.8-2.0g/cm³), glass fiber content (should be ≥4%), and fire resistance rating (must meet the Class A1 non-combustible standard). As a National High-Tech Enterprise, Qinglong's GRC products have passed the Guangdong Province Science and Technology Achievement Appraisal, and third-party authoritative testing reports are available to ensure material performance is consistent with project design requirements. Meanwhile, the material's weather resistance indicators, such as the number of freeze-thaw cycles (≥200), should be specified to adapt to different regional climate conditions.

2. Customized Production Details: Connecting Design and Implementation

The advantage of GRC lies in its design freedom. The contract should specify in detail the mold-making standards (e.g., surface flatness ≤2mm/m), texture replication precision (e.g., the realism level of stone-imitation effects), and machining tolerances for irregular components (recommended within ±3mm). Qinglong has a provincial-level engineering technology center and can achieve complex shapes such as double-curved surfaces and openwork reliefs through BIM technology and parametric design. The contract should clarify the division of responsibilities for detailed design to avoid cost disputes caused by design changes. In addition, the production cycle must match the project schedule, with the raw material procurement period, production scheduling, and response mechanism for urgent orders specified.

3. Full-Process Service Responsibilities: Ensuring Seamless Project Coordination

A quality GRC supplier should provide full-chain services covering "detailed design - manufacturing - construction and installation - after-sales maintenance." The contract must clarify installation guidance responsibilities, including on-site setting-out, anchoring solutions (e.g., material requirements for stainless steel connectors), and assembly precision (joint height difference ≤1mm). As a Grade II professional contractor for building curtain wall engineering, Qinglong's construction team has extensive high-altitude work experience, effectively reducing installation risks. Meanwhile, after-sales clauses should specify the warranty period (recommended no less than 5 years) and maintenance response time (e.g., arriving on site within 24 hours) to ensure long-term project stability.

4. Acceptance Standards and Dispute Resolution: Clarifying Boundaries of Rights and Responsibilities

The acceptance stage requires quantitative standards, such as appearance quality (no cracks or air bubbles, with color difference controlled at CIE LAB value ΔE≤3), dimensional deviations (length/width/thickness tolerance ±5mm), and mechanical performance re-inspection requirements. The contract should specify the method for selecting third-party testing institutions and the party bearing the costs to avoid acceptance disputes. In addition, the dispute resolution clause should clarify that negotiation is the preferred method; if negotiation fails, the matter shall be submitted to the arbitration institution at the project location to ensure efficient dispute resolution. Qinglong participated in formulating the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018) and can provide standardized acceptance process support.

Signing a GRC procurement contract is like building a "protective net" for the project. Clarifying the above clauses is key to ensuring project quality, controlling costs, and improving efficiency. As a Vice Chairman Unit of the GRC industry, Qinglong always maintains a meticulous and excellence-driven attitude, providing clients with full-cycle professional services from contract signing to project delivery, helping create safe, beautiful, and durable architectural works.
