How to Sign a Contract with a GRC Manufacturer to Protect Your Rights

In the field of architectural decoration, new materials such as UHPC, GRC, GRG, and GRP have become the first choice for many high-end projects thanks to their unique performance advantages. However, when signing contracts with GRC manufacturers, loopholes in the terms can easily lead to quality disputes, delivery delays, and other problems. Qinglong Group, drawing on 28 years of industry experience and full-chain service practice, explains in detail the key points of signing GRC contracts to help you effectively safeguard your rights and interests.

1. Clarify Material Performance and Quality Standards to Build a Solid Foundation for Cooperation

The contract must precisely define the core technical parameters of GRC materials, such as flexural strength (recommended no less than 20MPa), glass fiber content, bulk density, and fire resistance rating; industry standards such as the Technical Standard for Building Application of Glass Fibre Reinforced Cement (GRC) (JGJ/T423-2018) may be used as references. At the same time, require the manufacturer to provide reports issued by national-level testing institutions specifying the material's indicators for weather resistance, freeze-thaw resistance, and other aspects, to avoid acceptance disputes later caused by vague standards. Qinglong, as a company that has participated in formulating multiple GRC standards, recommends stating in the contract that "material performance complies with current national and industry standards" to control quality at the source.

2. Detail Design Development and Production Processes to Avoid Liability Disputes

The customized nature of GRC products determines the importance of the design development stage. The contract should specify that the manufacturer must have BIM technology application capabilities, carry out parametric design for complex shapes (such as double-curved surfaces and hollowed-out components), and submit the confirmation process and time limits for development drawings. For the production stage, the contract should stipulate mold quality, curing processes, and factory inspection standards; the manufacturer may be required to provide a production schedule and regularly submit actual workshop videos or photos. Qinglong's production base in Nanning, Guangxi has an annual capacity of 600,000 square meters; we recommend adding a "traceable production process" clause to the contract to ensure controllable quality for every batch.

3. Standardize Construction, Installation, and Acceptance Processes to Ensure Project Delivery

Construction and installation are critical to the success of GRC projects. The contract must specify the scope of installation the manufacturer is responsible for, the construction techniques adopted (such as 3D laser scanning positioning and modular installation), and safety measures, and agree on the installation precision tolerance (recommended ≤3mm). Acceptance should be carried out in stages, including material entry acceptance, concealed works acceptance, and final acceptance, with written confirmation documents signed at each milestone. Qinglong, as an enterprise holding Grade II professional contracting qualification for building curtain wall engineering, reminds customers to clearly specify in the contract the rectification deadline and liability for breach in case of failed acceptance, so as to avoid construction delays.

4. Clarify After-Sales Maintenance and Liability Division to Reduce Subsequent Risks

Quality after-sales maintenance is the guarantee of long-term cooperation. The contract should stipulate the warranty period for GRC products (recommended no less than 5 years) and clarify the manufacturer's repair obligations during the warranty period, such as crack repair and component reinforcement. At the same time, divide the responsibilities of both parties during use: damage caused by material quality problems shall be borne by the manufacturer, while damage caused by human factors or force majeure shall be negotiated separately. Qinglong has established a sound after-sales system and recommends adding a "24-hour response" clause to the contract to ensure timely handling of problems.

5. Ensure the Rigor of Contract Terms to Protect Legitimate Rights and Interests

When signing the contract, carefully verify the rights and obligations of both parties, including payment methods (installment payments based on production progress are recommended), delivery timelines, and liability for breach. For customized GRC projects, an "irrevocable design confirmation" clause should be added to prevent repeated client modifications from increasing costs. In addition, clearly specify the dispute resolution method and give priority to choosing the arbitration or litigation venue to reduce the cost of rights protection. As a national Specialized, Refined, Distinctive, and Innovative enterprise, Qinglong always treats every contract with the values of "honesty and collaboration." We recommend choosing a GRC manufacturer with industry qualifications and a good reputation to avoid risks at the very source of cooperation.

In summary, signing a contract with a GRC manufacturer requires balancing technical details with legal norms; by clarifying standards, detailing processes, and dividing responsibilities, both parties can achieve a win-win cooperation.
