1. Limitations of Traditional Metal Frame Construction Standards

Traditional metal frame construction lacks unified and rigorous industrial standards, resulting in uneven project quality and restricted industry upgrading. Most small and medium-sized building manufacturers adopt simplified production processes and low-cost material configurations to control project costs, leading to widespread performance defects in finished residential buildings.

In terms of material standards, traditional metal frame houses mostly use ordinary low-strength thin steel plates with single surface anti-rust treatment. These generic materials have poor tensile strength and weak resistance to extreme weather erosion. Under coastal salt spray, desert ultraviolet radiation, and seasonal typhoon environments, conventional metal frames easily suffer from surface rust, paint peeling, structural deformation, and component aging within a few years, greatly shortening building service life and threatening residential safety.

In production and processing standards, traditional metal frame components rely on semi-automatic mechanical processing and manual cutting, resulting in large dimensional errors. Most manufacturers fail to implement unified precision control standards, causing mismatched assembly gaps, loose structural connections, and unbalanced structural stress. Coupled with backward on-site welding construction processes, traditional metal frame houses are prone to welding cracks, residual structural stress, and local structural instability, bringing hidden safety hazards for long-term residence.

In quality control and construction management standards, the traditional metal frame construction industry lacks standardized process supervision and multi-dimensional quality verification mechanisms. Most manufacturers only conduct simple finished product appearance inspection, ignoring structural stress simulation, extreme weather resistance testing, and long-term durability verification. The lack of comprehensive quality control standards leads to inconsistent finished quality of metal frame houses, making it impossible to meet the high-standard requirements of modern residential projects for safety, durability, and comfort. These widespread industry shortcomings urgently require authoritative and systematic new standards led by leading enterprises such as Lida Group.
