Foshan Office Chair Explosion-Proof

Some office chairs in Foshan have failed safety tests due to the lack of explosion-proof steel plates, highlighting the need to focus on the quality, material, and certification marks of gas springs to ensure explosion-proof performance.

Some office chair products in the Foshan area have failed safety tests due to the absence of explosion-proof steel plates, such as those produced by Shanghai Xingaofan Furniture Manufacturing Co., Ltd. and the swivel chairs produced by Foshan Zhongge Furniture Industrial Co., Ltd.. The explosion-proof steel plate is a crucial safety component of hydraulic office chairs, designed to prevent fragments from penetrating the seat surface and causing personal injury in the event of an explosion caused by abnormal internal pressure or long-term aging of the gas spring. If not installed or installed improperly, the gas spring can become a "time bomb" under extreme conditions, posing a threat to user safety.

The explosion-proof performance of hydraulic office chairs should be evaluated based on the following core elements:
1. Gas Spring Quality: High-quality gas springs should be made of high-strength alloy steel with a precise internal structure, capable of stably withstanding dynamic pressure changes. Poor-quality gas springs may fail prematurely due to insufficient material strength or manufacturing defects during frequent lifting or when overloaded.
2. Material and Workmanship: The outer shell of the gas spring should be rust-proof, and the internal seals should be made of aging-resistant materials to prevent pressure abnormalities caused by corrosion or seal failure after long-term use. Some products further enhance safety by increasing the thickness of the explosion-proof steel plate or adopting a double-layer structural design.
3. Load-Bearing Capacity: The rated load-bearing capacity of the gas spring should match the intended use of the chair. For example, ordinary office chairs typically have a load-bearing capacity of 100-120 kilograms, while products designed for larger users or high-intensity use scenarios should have a higher load-bearing rating. Overloading can accelerate wear on the gas spring and increase the risk of explosion.

When purchasing, it is essential to check the brand and certification marks of the gas spring:

• Prioritize products that have passed international safety certifications (such as Germany's TÜV or the United States' BIFMA) or domestic standards (such as GB/T 10357.4-2013);
• Observe whether the surface of the gas spring has clear manufacturer markings, model numbers, and load-bearing parameters;
• Avoid purchasing products without a brand, certification, or those priced significantly below the market average, as these may use recycled materials or simplified processes to reduce costs.

In addition, avoid frequently and rapidly adjusting the chair's height during daily use, and regularly inspect the gas spring for cracks, air leaks, or unusual noises. If any abnormalities are detected, stop using the chair immediately and contact after-sales service for replacement.
