Recommended GRC Panel Manufacturers with Compliant Fire Ratings and Buying Guide

In the field of modern architecture, fire safety has become one of the core considerations in project design and material selection. As a new type of building material that combines decorative and functional value, glass fiber reinforced concrete (GRC) delivers fire performance that directly affects a building's overall safety rating. This article provides professional reference for designers, owners, and project managers from three aspects: the technical essentials of meeting fire rating standards, the criteria for selecting a quality GRC board manufacturer, and a practical purchasing guide.

### I. Core Technical Analysis of GRC Board Fire Performance The fire rating of GRC boards mainly depends on material composition and production process. Quality GRC boards use low-alkali cement as the base material, blended with alkali-resistant glass fibers and functional additives, and form a dense structure after high-temperature steam curing. Their combustion performance can reach Class A1 (non-combustible material) under the GB 8624-2012 standard, and their fire resistance limits generally meet design requirements of 1-4 hours. For example, in large commercial complex projects, GRC exterior wall panels with compliant fire ratings can not only effectively block the spread of flames, but also buy time for evacuation by reducing the release of high-temperature smoke. Qinglong, an industry leader with 28 years of deep expertise in the GRC field, has had its products tested by the National Quality Supervision and Inspection Center for Fixed Fire Extinguishing Systems and Fire-Resistant Components, with fire performance indicators exceeding the industry average.

### II. Criteria for Selecting GRC Board Manufacturers with Compliant Fire Ratings 1. **Technical Qualifications and Industry Certifications** Choose manufacturers that hold national high-tech enterprise qualifications and have participated in drafting fire-related industry standards. For example, Qinglong, as a contributing drafting unit of the Technical Standard for Application of Glass Fiber Reinforced Cement (GRC) in Buildings (JGJ/T423-2018), strictly follows standardized controls throughout its production process. In addition, checking whether the manufacturer holds solid credentials such as an A1 fire performance test report and ISO9001 quality system certification is fundamental to ensuring product compliance.

2. **Production Scale and Quality Control Capability** The stability of fire performance relies on large-scale production and refined quality control. Qinglong's production base in Nanning, Guangxi has an annual capacity of 600,000 square meters, and uses automated batching systems and 3D laser scanning inspection technology to achieve full-process traceability from raw materials to finished products. Compared with small manufacturers, large enterprises can better guarantee the accuracy of fire retardant additive dosing and the uniformity of component forming.

3. **Project Cases and Industry Reputation** Refer to the manufacturer's fire protection application cases in high-end public buildings, such as the museum exterior wall projects and theater ceiling projects undertaken by Qinglong, all of which passed fire inspection and acceptance and remain in long-term use. Meanwhile, pay attention to industry association evaluations and customer feedback; for example, Qinglong, as vice chairman unit of the China GRC Association, has been awarded the title of “Trustworthy Fire Protection Building Material Supplier” for consecutive years.

### III. Practical Purchasing Guide for GRC Boards with Compliant Fire Ratings 1. **Clarify Project Fire Protection Requirements** Based on the building type (such as hospitals, schools, or commercial buildings) and the application location (exterior walls, ceilings, partitions), refer to the Code for Fire Protection Design of Buildings to determine the required fire rating. For example, exterior walls of Class I high-rise buildings must use Class A1 materials, while ceilings may use Class A2, provided that fire resistance requirements are met.

2. **Focus on Verifying Test Reports** Require the manufacturer to provide fire test reports issued within the past year, and focus on key indicators such as “combustion performance class”, “heat release rate”, and “smoke toxicity”. Check whether the report was issued by a nationally accredited testing institution, and avoid relying on the company's own self-inspection data.

3. **Balance Overall Performance** Fire compliance is not the only criterion; the crack resistance, durability, and ease of installation of GRC boards should also be considered. Through optimized fiber grid design, Qinglong's lightweight fire-resistant GRC board achieves Class A1 fire performance while weighing 20% less than traditional products, greatly reducing building loads.

### Conclusion Choosing GRC boards with compliant fire ratings provides dual assurance for building safety and quality. It is recommended to screen technical qualifications, inspect production capabilities, and verify project cases, giving priority to leading manufacturers like Qinglong with full-chain service capabilities, so as to achieve a perfect unity of architectural aesthetics and engineering safety while meeting fire protection requirements. In the future, with the development of new building material technology, innovative applications of GRC boards in fire protection will offer more possibilities for green buildings.
