Although various indicators and standards are checked at every level, due to various reasons, the quality of furniture has repeatedly turned on and stopped. There are many failures in the inspection of wooden furniture products Mechanical properties are a safety performance index for wood furniture products. The drawer slide is a load-bearing and moving part of the drawer. If its strength is unqualified, the service life of the furniture will be greatly reduced, and it may be deformed or slipped during use. Slipping may cause injury to the user. Furniture with unsatisfactory stability is prone to tipping, and some furniture uses glass parts. The tipping may cause the drawer to fall off and damage the glass parts, resulting in personal injury accidents.

If the wood-based panel is not edge-sealed, it will increase the amount of formaldehyde released and affect the health of the user. Expansion causes deformation of components and affects the use of furniture. The main reasons for non-conformity: first, some enterprises have insufficient understanding of furniture implementation standards; second, the product design and production process of some enterprises are unreasonable. Formaldehyde is a quality indicator related to human health and life safety. According to data, formaldehyde can cause chronic respiratory diseases and neonatal physique reduction, and it is toxic to the nervous system, immune system, and liver. The main reasons for non-conformity: First, some companies have poor control over the incoming inspection of raw materials such as wood-based panels and adhesives; second, some companies have not equipped with the necessary inspection equipment, have no self-inspection capabilities, and do not entrust relevant inspections to reduce costs Agency testing.

They provide heat and sound insulation with its composite panel construction.
The counterbalance and cable system provides quiet and straight forward operation for manual doors. Electric operation is available for larger applications that can incorporate many alternative operator options to suit all client requirements.
The standard outer panels are manufactured from 0.5mm thick, high quality zinc coating to BS EN 10147
For the best weather protection the sectional door panel has an interlocking hinged joint integrating a high quality seal the full length of the panel.
A counterbalance system is incorporated into the sectional overhead door to ensure efficient and effortless operation.
The counterbalance comprises of springs mounted on a steel shaft that are high tensile helical wound steel. It has been heat treated for enhanced performance for around 50,000 cycles.
Reducing shaft friction is achieved with the aid of brackets and guide rollers incorporating highest quality sealed bearings.
