What acceptance documents are required at product delivery?

In the project delivery of new architectural decorative materials such as UHPC, GRC, GRG, and GRP, the completeness of acceptance documents directly affects project quality and the definition of later maintenance responsibilities. Qinglong Group, with 28 years of full-chain experience in detailed design, manufacturing, construction and installation, and after-sales maintenance, has always regarded a standardized acceptance document system as a key link in ensuring project quality. 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 Certification Documents: Building a Solid Foundation for Product Compliance

UHPC (Ultra-High Performance Concrete), GRC (Glass Fiber Reinforced Concrete), GRG (Glass Fiber Reinforced Gypsum), and GRP (Glass Reinforced Thermosetting Plastic, i.e., fiberglass) are customized decorative materials whose physical and mechanical properties must be verified through authoritative testing. At delivery, the **material factory certificate of conformity** must be provided, clearly indicating product model, batch, production date, and applicable standards (for example, GRC must comply with the Technical Standard for Architectural Applications of Glass Fiber Reinforced Cement (GRC) JGJ/T423-2018, and UHPC must meet the industry standard General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)). Meanwhile, **third-party test reports** are indispensable, covering key indicators such as flexural strength, elastic modulus, weather resistance, and fire rating—taking Qinglong UHPC as an example, its compressive strength can exceed 150MPa, and the test report must clearly present this core parameter. In addition, for special requirements such as the environmental friendliness of GRG and the corrosion resistance of GRP, corresponding specialized test documents must be supplemented to ensure that material performance highly matches design requirements.

### II. Detailed Design and Production Process Documents: A Bridge Connecting Design and Construction

The customized nature of new decorative materials determines the importance of detailed design documents. At delivery, **detailed design drawings** must be submitted, including component breakdown drawings, node detail drawings, installation positioning drawings, etc., and must bear the official seals of the design institute and Qinglong's technical department to ensure consistency with the original design scheme. For complex shapes (such as double-curved GRG ceilings and hollow UHPC exterior wall panels), **3D model data** (such as BIM models and Rhino parametric files) should also be provided to assist contractors in precise installation. The production stage requires **production process records**, covering raw material ratios, molding processes, curing conditions, etc. For example, Qinglong GRC components use automated spray molding technology, and their production records must reflect key process parameters such as glass fiber content (usually ≥5%) and water-cement ratio. If the project involves special-shaped components or special surface treatments (such as stone-like textures or light-transmitting effects), **sample confirmation documents** must also be included in the acceptance materials as an intuitive standard for later quality acceptance.

### III. Construction Installation and Safety Assurance Documents: Ensuring Project Implementation Quality

Construction and installation is the key link in translating material performance into architectural effects. At delivery, an **installation construction plan** must be provided, clarifying technical points such as hoisting techniques, anchoring methods, and joint treatment; especially for the installation of exterior wall components such as UHPC and GRC, calculation explanations for wind load resistance and seismic performance must be included. **Concealed work acceptance records** are equally important—such as embedded part positions and anti-corrosion treatment of connection nodes—and must be signed and confirmed by the supervision unit. To ensure construction safety, **product weight and transportation/installation guidelines** are essential; for example, Qinglong GRP daylighting roof components, being lightweight and high-strength (density approximately 1.8g/cm³), must have hoisting points and load-bearing limits marked. In addition, for large-scale projects, an **on-site installation quality checklist** should be provided, recording measured data such as component verticality and joint flatness, to ensure compliance with the Standard for Acceptance of Construction Quality of Building Decoration Engineering GB50210.

### IV. After-Sales Maintenance and Traceability Documents: Building a Full Life-Cycle Service System

As a full-chain service provider of "detailed design-production-construction-maintenance", Qinglong Group provides an **after-sales maintenance manual** at delivery, clarifying the maintenance requirements of different materials (for example, GRG must avoid humid environments, and UHPC requires regular cleaning of surface stains) and warranty periods (usually 5-10 years). To achieve quality traceability, **product identification documents** are indispensable; for example, UHPC components in some high-end projects are embedded with RFID chips recording production batch, installation location, and other information for easier later maintenance. In addition, **technical training materials** can help owners master basic maintenance skills, while **emergency response plans** (such as repair procedures for cracked GRC components) can quickly respond to unexpected problems. These documents not only reflect Qinglong's service commitment of "meticulousness and excellence", but also provide a guarantee for the long-term stable operation of projects.

The standardized delivery of acceptance documents is an inevitable requirement for the professionalization and standardization of the new architectural decorative materials industry. Leveraging 28 years of industry experience, Qinglong Group integrates full-process information on material performance, detailed design, construction and installation, and after-sales maintenance into systematic acceptance documents, providing traceable evidence for project quality while demonstrating the professional strength of a national high-tech enterprise. For designers and owners, complete acceptance documents are not only the basis for engineering compliance, but also an important consideration when selecting a reliable UHPC/GRC/GRG/GRP supplier.
