How Long Do GRC Manufacturer Products Last? Answers from 28 Years of Industry Experience

"How long can GRC products be used? Quality products have a service life of more than 20 years!"

When selecting GRC products, service life is one of the core concerns of customers, as it directly relates to the long-term benefits of a project. As a UHPC/GRC/GRG/GRP material supplier with 28 years of deep industry experience, Qinglong Group draws on its production technology and project practice to give a detailed explanation of the service life of GRC products and the key factors affecting it.

1. Typical service life of GRC products

Quality GRC products have a normal service life of more than 20 years, and in some projects this can even reach 30 years. This conclusion is based on the characteristics of GRC materials and the production processes of quality manufacturers—GRC uses alkali-resistant glass fibres to reinforce a cement matrix, combining the durability of cement with the tensile strength of glass fibre. As long as production processes are standardised and material proportions are scientifically formulated, GRC can be used stably over the long term.

The GRC products of Qinglong Group have undergone rigorous durability testing, including ageing resistance, freeze-thaw resistance, acid and alkali resistance and other tests, with all indicators far exceeding industry standards. Taking the Sichuan Panzhihua Third Front Construction Culture and Tourism Demonstration Project as an example, the GRC curtain wall panels supplied by Qinglong are guaranteed to keep their strength without ageing or cracking for more than 20 years; after many years of use, the products still perform stably.

By contrast, inferior products from some small manufacturers, due to poor materials and non-standard processes, may have a service life of only 3-5 years and are prone to cracking, fading, loss of strength and other problems, increasing later repair costs.

2. Three key factors affecting the service life of GRC products

The service life of GRC products is not a fixed value; it is mainly affected by three core factors. The first is product quality, including material selection, formula design and production processes, which is the foundation that determines service life. Qinglong Group uses high-quality alkali-resistant glass fibres, high-grade cement and carefully selected aggregates, combined with scientific formulas and mature processes, to guarantee product durability at the source.

The second is the service environment, as different environments cause different degrees of wear to GRC products. In coastal areas, high humidity and salt spray accelerate product ageing, so GRC products with stronger corrosion resistance should be chosen; in severely cold regions, freeze-thaw cycles affect product structure, so products with excellent freeze-thaw resistance should be selected. Qinglong Group can customise differentiated GRC products according to different service environments to extend service life.

The last is installation and maintenance. Standard-compliant installation prevents uneven stress on products, and regular maintenance allows potential problems to be identified and addressed in time. Qinglong Group provides professional installation guidance and after-sales maintenance services for every project, ensuring products are installed properly and inspected regularly during later use, thereby extending service life.

3. Practical tips for extending the service life of GRC products

To keep GRC products in long-term stable use, start from three stages: selection, installation and maintenance. When selecting, give priority to capable manufacturers with a good reputation like Qinglong, and check the products' durability test reports and related project cases; when installing, strictly follow the installation specifications provided by the manufacturer to ensure secure fixing and reserved expansion joints, avoiding damage caused by improper installation; when maintaining, regularly clean dust and dirt from the product surface, avoid impact from sharp objects, and repair any minor damage promptly.

The after-sales team of Qinglong Group provides customers with detailed maintenance guides, regularly follows up on project usage and offers professional maintenance advice. Taking the Shanghai Xinghewan Project as an example, Qinglong's GRC components have been in use for more than ten years; through regular maintenance, their appearance and performance remain good, with a service life far exceeding expectations.

When selecting GRC products, do not focus only on short-term price; pay more attention to product quality and service life. Only by choosing products from quality manufacturers, together with standard-compliant installation and regular maintenance, can GRC products deliver their maximum value and bring long-term benefits to a project.
