Does GRC Meet Fire Performance Standards? Authoritative Certification of GRC Fire Performance

GRC products have excellent fire resistance, with a combustion performance rating of Class A (A1). As a non-combustible material, their fire resistance limit can reach over 2 hours. This outstanding fire performance has led to their wide application in various types of buildings.

According to testing by the National Quality Supervision and Inspection Center of Fire-resistant Building Materials, Qinglong GRC products achieve a Class A (A1) combustion performance rating, and do not burn or produce toxic gases when exposed to fire. Fire resistance tests show that a 20mm thick GRC panel can withstand fire for up to 120 minutes, with temperature rise on the unexposed face ≤140℃ and integrity fully maintained. These properties fully meet the requirements of the Code for Fire Protection Design of Buildings. In a high-rise residential project in Shanghai, the GRC exterior wall system successfully passed fire inspection, providing reliable protection for building safety.

Combustion Performance Rating

GRC is composed of inorganic materials such as cement, sand, and fibers, making it a non-combustible material with a Class A combustion performance rating. It does not burn or produce toxic smoke when exposed to fire, making it safe and reliable.

Fire Resistance Performance

A 20mm thick GRC panel has a fire resistance limit of up to 2 hours, meeting the fire compartmentation requirements of most buildings. The fire resistance limit can be further improved by increasing the thickness or adding reinforcement layers.

Performance Stability at High Temperatures

Under high temperature, GRC experiences little strength loss. After 1 hour at 600℃, the compressive strength retention rate remains above 70%, demonstrating good high-temperature stability.

Adaptability to Fire Protection Construction

GRC can be easily combined with other fire-resistant materials to form a complete fire protection system. This flexibility gives it unique advantages in complex fire protection constructions.

The excellent fire performance of GRC has been certified through authoritative testing. Choosing GRC products in building design provides strong protection for building safety. The fire performance of Qinglong GRC products fully complies with national standards.
