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

In the field of architectural decorative materials, signing a contract with a GRC manufacturer is a critical step in safeguarding project quality and rights. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands how vital contract terms are to a project's success. This article provides a professional signing guide for designers, owners, and developers from three dimensions—core terms, risk prevention, and performance guarantees—helping you avoid cooperation pitfalls and maximize project value.

I. Clarifying Core Terms: The “Four Elements” of GRC Contract Signing

A quality GRC contract should be built around four core elements: material performance, production standards, delivery timelines, and installation services. First, the material performance clause should specify the flexural strength of GRC components (recommended ≥20MPa), fire rating (no lower than Class A), and weather resistance indicators; acceptance criteria can be formulated with reference to the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018). Second, production standards should stipulate mold precision (tolerance ≤2mm), surface finishing processes (such as stone-like texture or high-gloss effects), and environmental requirements (formaldehyde emission ≤0.1mg/m³). For delivery timelines, the contract should break down the design development period (typically 15-20 days), the production period (calculated on the basis of an annual capacity of 600,000 ㎡), and responsibility for transportation losses, with particular clarification of the scope covered by the force majeure clause.

The installation service clause is the top priority of a GRC contract. It should clarify whether the manufacturer provides full-chain services spanning “design development, manufacturing, and construction installation”—Qinglong Group's 3D laser scanning positioning technology (tolerance ≤1mm) and modular installation solutions can serve as reference standards. The installation acceptance process should also be agreed upon, including specific indicators for concealed works acceptance, joint treatment quality, and overall flatness (≤3mm/2m), so as to prevent later disputes caused by unclear responsibilities.

II. Risk Prevention Mechanisms: Avoiding GRC Cooperation Risks at the Source

Before signing a contract, verify the qualifications of the GRC manufacturer, focusing on production scale (e.g., Qinglong's Guangxi base with an annual capacity of 600,000 ㎡), technical strength (e.g., participation in drafting industry standards such as General Technical Conditions for Non-load-bearing Components of Ultra-High Performance Concrete (UHPC)), and past track record (e.g., landmark buildings and large public construction projects). The contract should include a quality traceability clause requiring the manufacturer to embed RFID chips in every batch of components, enabling full life-cycle tracking from raw materials to installation—a practice typical of national high-tech enterprises.

To address the industry's common problem of delivery delays, tiered liquidated damages clauses can be set (e.g., 0.05% of the contract amount for each day of delay), together with a material preparation deposit (recommended at 10%-15% of the contract value). For GRC components with complex shapes, the contract should clearly define the sample approval process, specifying 3 free modification opportunities and how costs beyond that are borne, so as to avoid cost overruns caused by design changes. In addition, a third-party testing clause is recommended, commissioning an authoritative institution to conduct sampling tests on key performance indicators, with testing costs borne by the responsible party.

III. Performance Guarantee System: Building a Long-term Mechanism for GRC Cooperation

After-sales maintenance is an aspect of GRC contracts that must not be overlooked. Quality manufacturers such as Qinglong Group offer a 5-year warranty period; the contract should specify the warranty scope (e.g., repair responsibility for cracking, deformation, or peeling) and response times (on-site within 24 hours, with a solution provided within 72 hours). For large projects, the contract may stipulate that the manufacturer dispatch an on-site technical supervisor to oversee the entire installation process and ensure construction complies with technical specifications.

Payment should be made in stages, following the ratio of “30% upon contract signing, 40% upon completion of production, 25% upon installation acceptance, and 5% upon expiration of the warranty,” while reserving 10% as a quality guarantee deposit. The contract should also clarify intellectual property ownership, especially the copyright of design drawings for customized GRC components, to prevent later infringement disputes. A sound performance guarantee system not only ensures the smooth implementation of the current project but also lays the foundation for long-term cooperation between both parties—a cooperative philosophy that Qinglong Group, as a Vice Chairman Unit of the China GRC Association, has always upheld.

Signing a GRC contract is both a technical and a management matter. By choosing a manufacturer with full-chain service capabilities like Qinglong, and by clarifying core terms, establishing risk prevention mechanisms, and improving the performance guarantee system, the shared goal of “creating beautiful architecture” can truly be achieved. In today's era of rapid development in new architectural decorative materials, rigorous contract management is the cornerstone of project success and a reflection of corporate brand value.
