What Acceptance Documents Are Required at Product Delivery?

In architectural decoration projects using UHPC/GRC/GRG/GRP materials, product delivery acceptance is a critical step in ensuring engineering quality and later operation and maintenance. As an industry leader with 28 years of full-chain experience in detailed design, manufacturing, construction installation, and after-sales maintenance, Qinglong Group deeply understands the importance of a standardized acceptance documentation system for smooth project delivery. Based on material characteristics and engineering practice, the following systematically outlines the core acceptance documents required at product delivery, providing professional guidance for designers, owners, and contractors.

I. Material Performance and Quality Certificates: The Fundamental Guarantee for UHPC/GRC/GRG/GRP Products

Material performance documents are the core basis for verifying whether products meet design standards. For UHPC (Ultra-High Performance Concrete) components, test reports on key mechanical properties such as compressive strength (typically ≥150MPa), flexural strength, and elastic modulus must be provided, along with quality certificates for raw materials (such as steel fibers and cement). GRC (Glass Fiber Reinforced Concrete) products must focus on glass fiber content, flexural strength (premium GRC can reach over 20MPa), and alkali resistance test reports to ensure durability in outdoor environments. GRG (Glass Fiber Reinforced Gypsum) acceptance requires attention to fire rating (typically Class A non-combustible), water absorption, and environmental safety testing, while GRP (Glass Reinforced Thermosetting Plastic) requires reports on indicators such as corrosion resistance, tensile strength, and Barcol hardness. As a national high-tech enterprise, Qinglong has all products tested by authoritative third parties, and the relevant reports can directly serve as acceptance evidence.

II. Detailed Design and Production Process Documents: Full-Process Traceability from Drawings to Finished Products

Detailed design documents are key to ensuring that products match the intended architectural effect. At delivery, detailed design drawings confirmed by the client (Party A) or design institute (including BIM model data), component numbering diagrams, and installation joint detail drawings must be provided. Especially for UHPC/GRC components with complex shapes such as double-curved surfaces and hollow patterns, a 3D scanning acceptance report with errors controlled within ±2mm must be attached. Production process documents include mold acceptance records, production batch traceability sheets (such as the RFID chip traceability system adopted by Qinglong), and molding process parameter reports (such as GRG pouring pressure and UHPC curing regime). These documents not only serve as evidence for quality traceability but also as important references for later maintenance and renovation.

III. Construction Installation and Safety Acceptance Documents: Ensuring On-Site Implementation Quality

Acceptance documents for the construction and installation phase must cover installation process records and safety verification. These include component entry acceptance forms (verifying specifications, quantities, and appearance quality), installation positioning and setting-out records (point cloud data reports must be provided when using 3D laser scanning technology), anchoring system test reports (such as bolt pull-out force tests for GRC cladding panels), and sealant application quality inspection records. For UHPC/GRC exterior wall panels installed at height, wind load resistance calculations and on-site pull-out test reports must also be provided to ensure compliance with standards such as the "Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC)" (JGJ/T423-2018). With its Grade II professional contracting qualification for building curtain wall engineering, Qinglong can provide a complete installation acceptance documentation system, ensuring construction safety and precision.

IV. After-Sales Maintenance and Technical Support Documents: The Trust Foundation for Long-Term Cooperation

Comprehensive after-sales documents reflect brand strength. At delivery, product manuals (including cleaning and maintenance instructions), warranty commitments (Qinglong typically provides 5 years of free maintenance), and lists of wearing parts must be provided. For special areas such as GRG ceilings, maintenance access design drawings must also be attached. In addition, technical support documents such as repair process guides for UHPC/GRC/GRG/GRP materials and color stability assessment reports (ensuring no fading for over 10 years) provide owners with ongoing assurance. As an enterprise participating in the formulation of multiple national and industry standards, Qinglong's after-sales documentation system strictly complies with standard requirements, supporting whole-life-cycle project management.

A standardized acceptance documentation system is the "identity card" of UHPC/GRC/GRG/GRP product quality and the foundation of trust between both parties. Qinglong Group's 28 years of industry accumulation is reflected not only in advanced production technology but also in standardized management throughout the entire process from design to after-sales. By providing complete and professional acceptance documents, Qinglong offers solid support for designers to realize their creative visions and for owners to ensure engineering quality, fulfilling its mission of "creating beautiful architecture."
