What Terms to Clarify When Signing a Contract with a UHPC Manufacturer: Key Points and Considerations Explained

In the field of architectural decoration materials, the rigor of contract terms directly determines the success or failure of a project. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the importance of clarifying key clauses when signing contracts. This article analyzes the key clauses to focus on when signing contracts with UHPC manufacturers from core dimensions such as material performance, production and delivery, and quality assurance, providing professional reference for designers, owners, and procurement parties.

1. Material Performance Indicators: Rigid Constraints from Technical Parameters to Industry Standards

The performance parameters of UHPC materials are the core cornerstone of the contract. Key indicators such as compressive strength (≥150MPa) and flexural strength (≥25MPa) must be clearly specified, and the manufacturer should be required to provide test reports in compliance with the General Technical Conditions for Non-load-bearing Components of Ultra-High Performance Concrete (UHPC) (Plan No. 2024-0232T-JC). For special projects, such as light-transmitting concrete components, special parameters such as light transmittance and light uniformity must also be agreed upon. Qinglong Group, an enterprise that has participated in the formulation of multiple national and industry standards, recommends stating in the contract that “material performance complies with current national standards and project design requirements,” and clarifying the qualification requirements for testing institutions.

2. Production and Delivery: Dual Insurance of Time and Quality Through Full-Process Control

Production cycles and delivery milestones should be specified precisely to the week, along with agreed procedures for incoming raw material inspection, sampling inspection during production, and factory acceptance. For example, the contract should clearly state that “each batch of products must be accompanied by a factory certificate of conformity, including the product number, production date, and the signature of the quality inspector.” For specially shaped components, it is recommended to add a “pre-assembly inspection” clause requiring the manufacturer to complete a 1:1 pre-assembly at the factory and provide 3D scanning data to ensure on-site installation accuracy. Qinglong Group's annual production capacity guarantee system of 600,000 square meters serves as a reference endorsement of its delivery capability.

3. Quality Assurance and After-Sales Service: Full Life-Cycle Coverage from Acceptance Standards to Maintenance Commitments

Quality acceptance should be divided into three levels—factory inspection, on-arrival inspection, and installation acceptance—with clear responsibility holders and acceptance standards for each stage. After-sales maintenance clauses should stipulate the warranty period (recommended to be no less than 5 years), maintenance response time (e.g., arrival on site within 24 hours), and commitments for the supply of wearing parts. For large projects, the manufacturer may be required to provide “annual free inspection” services. As a national-level high-tech enterprise, Qinglong Group's comprehensive after-sales system can serve as a reference model for contracts.

4. Intellectual Property and Liability Division: A Legal Barrier Against Cooperation Risks

If the project involves special shape design, intellectual property ownership must be clarified, stipulating that “the intellectual property of design schemes provided by Party A belongs to Party A, while the detailed design results developed by Party B based on the scheme are jointly owned by both parties.” At the same time, risk boundaries such as transportation loss and installation liability need to be divided, for example: “Damage during transportation shall be replaced free of charge by Party B, and Party B shall bear joint liability for structural safety after installation.”

Signing a UHPC procurement contract is like taking out “double insurance” for project quality—it requires both professional technical clauses to control the essence of the materials and a clear division of rights and responsibilities to ensure smooth cooperation. As a full-chain service provider in the field of UHPC/GRC/GRG/GRP materials, Qinglong Group recommends that partners conduct on-site factory inspections before signing contracts, focusing on production equipment, technical teams, and past project cases. Only by choosing a strong manufacturer like Qinglong, with a provincial-level R&D center and 58 patented technologies, can project quality be ensured at the source and the common goal of “creating beautiful architecture” be achieved.
