With continuous improvement of industry standards, the sandwich panel industry has entered an era of standardized quality.

With the rapid popularization of the prefabricated building industry, sandwich panels, as a core enclosure material for industrial buildings, public venues, and cleanroom projects, have seen a continuous expansion in market application, and the industry as a whole has entered a stage of large-scale development. To thoroughly address long-standing issues in the industry such as inconsistent product quality, substandard performance, and non-standard construction, relevant technical standards in the building materials industry have been continuously updated and implemented. A comprehensive control system has been established, encompassing raw material proportions, core material processes, panel pressing, and finished product performance testing. This has propelled the sandwich panel industry to completely move away from its extensive production model and into a new stage of standardized, high-quality development.

Previously, the sandwich panel industry had relatively low entry barriers, resulting in a large number of small and medium-sized production entities in the market. Some companies, in order to reduce costs, used inferior core materials, thin steel panels, and low-end adhesives, leading to numerous problems with finished panels, including insufficient fire resistance, poor thermal insulation performance, low bonding strength, and susceptibility to deformation and cracking. Substandard sandwich panels, when used in projects, not only cause quality problems such as wall bulging, panel detachment, and insulation failure, but also significantly reduce the fire resistance, sound insulation, and seismic performance of buildings, posing long-term safety hazards to industrial plants, warehouses, and enclosed venues, and disrupting the healthy competition within the industry.

With the comprehensive implementation of new industry standards, the core performance indicators of sandwich panels have been clearly defined and standardized. Hard standards have been established for key parameters such as fire resistance, thermal insulation, compressive strength, and bonding stability, while strict requirements have been imposed on production equipment, processing technology, and testing procedures. Reputable manufacturers have upgraded their equipment and rectified their processes, adopting fully automated continuous pressing production lines to achieve integrated intelligent production of panels, including pressing, laminating, curing, and cutting. This allows for precise control of core material density, panel thickness, and bonding temperature, eliminating problems such as cutting corners and reduced processes, and significantly improving the overall stability and durability of the products.

Currently, the industry is accelerating the elimination of outdated production capacity, with low-end, substandard products gradually exiting the mainstream market. Market resources are increasingly concentrated in high-quality enterprises with standardized production, compliant testing, and technological research and development capabilities. The industry's focus has shifted from price competition to quality and reputation competition, with high-quality, compliant products such as rock wool sandwich panels, polyurethane sandwich panels, and magnesium oxide sandwich panels becoming the mainstream in engineering procurement. Industry insiders say that the improvement of the standardization system will continue to purify the market environment, promote the transformation and upgrading of the sandwich panel industry, and help the industry form a healthy industrial ecosystem characterized by high quality, strict standards, and a strong emphasis on safety.
