Fire-resistant glass has good light transmission properties and fire resistance, heat insulation and sound insulation properties. Common fire-resistant glass consists of laminated fireproof glass, wire-bonded fireproof glass and hollow fireproof glass. Many buyers of single-piece fireproof glass only care about the price of fireproof glass, but they ignore many important purchase considerations. Here are some tips for you to be a savvy purchaser of fireproof glass. First, the purchase of applicable products: single piece of fire-resistant glass, according to the thickness is divided into 6mm, 8mm, 10mm, 12mm, etc., according to the fire rating is divided into I (90 minutes), II (60 minutes), III (45 minutes) Grade IV (30 minutes). Which specific choice is not only based on the strength (or thickness), but also should be carefully selected to see the fire-fighting acceptance requirements of the fire rating. High-strength monolithic antimony potassium fireproof glass is more fire-resistant, stronger, and more stable than ordinary monolithic fire-resistant glass due to its dual chemical and physical treatment. Second, choose qualified manufacturers: As a result of fire protection, environmental protection, registered capital and other conditions, the registration of fire-fighting glass production enterprises, many companies that sell fire-resistant glass are registered as trade or sales-oriented enterprises, or no fire-proof glass is produced in the business scope of the license. Qualifications, some companies simply do not have business registration, such companies do not have the production conditions, of course, it is impossible to produce qualified fire-resistant glass products. The purchaser should understand the business status of the purchaser through a field visit to the factory and request that he produce the original (or copy) of the business license to prevent him from being deceived. Third, the purchase of products to check whether the sampling report and the record: The current fire department more stringent use of fire products, requiring production, sales and use of the fire equipment used by the life-long responsibility, if accidentally used forged fire products The certificate or certificate will bear a great deal of fire acceptance risk and future accident liability risk. According to the fire safety regulations, it must pass the sampling inspection of the public security fire department, and hold the National Fireproof Material Inspection Center or the national fixed fire extinguishing system and the refractory component quality inspection center. The company that produces the type inspection report within the validity period can produce fireproof glass. The use of inspection reports is generally for a period of three years. Inspection reports are generally filed with the quality inspection center and the provincial fire brigade. The inspection report should show the contact number and address of the quality inspection center to facilitate the authenticity of the report. The purchaser must ask the manufacturer whether he can present the original inspection report and provide the telephone number of the filing agency for verification. Fourth, at the time of purchase, it is best to ask the manufacturer to issue "certification of supply of fire products": in order to implement the spirit of the instructions of the Fire Bureau of the Ministry of Public Security on strengthening the supervision and management of the quality of fire products, and to regulate the market behavior of production, sales, installation and use of fire products. All provinces have correspondingly implemented the certification system for the supply of fire-fighting products, and established and implemented a credit system for fire protection products, which specifically includes the following points: 1. For fire-fighting products circulated in various provinces, their production units should fill in the “certification of supply of fire-fighting products†at the same time when they supply fire-fighting products to the purchaser. 2. When each sales and installation enterprise supplies fire-fighting products to the user, the product manufacturing enterprise shall be required to fill in the "certificate of supply of fire-fighting products." 3. The “certificate of supply of fire products†must be in one-to-one correspondence with the specific supply project or user unit. Each construction and user entity should submit the “certification of supply of fire protection products†along with other acceptance materials for completion acceptance of fire protection projects. Send public security fire control agencies for verification. 4. Fire-fighting products provided by production-free enterprises as "certification for the supply of fire-fighting products" are regarded as counterfeit products. Therefore, according to the above system, when purchasing a single piece of fireproof glass, it is better to ask the manufacturer to issue the "certification of supply of fire protection products" with the goods. Considering the product's cost performance, single-piece fire-resistant glass is a high-tech product. The production process is relatively complicated. The production cost is mainly affected by the production scale and equipment conditions of the company. Buying a single piece of fire-resistant glass is best considered in combination with product quality and selling price.
