Below are two industry news pieces focusing on China’s domestic policy dynamics and international standard revisions, respectively, with authoritative source links attached for further reference.
1. Domestic News (China): Multiple Ministries Jointly Release Building Materials Growth Plan; Q235B Pipes Become Key Infrastructure Materials
Core Content: On September 24, 2025, China’s Ministry of Industry and Information Technology (MIIT) and other departments issued the Work Plan for Stabilizing Growth in the Building Materials Industry (2025–2026). The plan explicitly aims to drive the growth of green building materials and advanced inorganic non-metallic materials, targeting over RMB 300 billion in green building materials revenue by 2026.
Notably, the plan emphasizes optimizing the supply structure of construction steel. As a low-carbon, cost-effective material, Q235B Pipe has been designated as a priority product for key projects such as urban pipeline renovation and UHV power transmission. For example, in the pipeline renovation project of the Chengdu-Chongqing Twin City Economic Circle, Q235B straight-seam welded pipes have replaced traditional cast iron pipes due to their corrosion resistance and weldability. Each pipe can bear a load of 8 tons, reducing overall costs by 15%.
Additionally, the plan strengthens quality supervision for steel products: Q235B Pipe must undergo spectral testing to ensure material purity, preventing safety hazards caused by mixed recycled materials.

2. International News (EU): EU Updates EN 74-1:2025 Scaffolding Coupler Standard, Impacting Global Scaffolding Screwed Coupler Design
Core Content: On October 16, 2025, the European Union released the revised standard EN 74-1:2025 — Requirements and Test Methods for Couplers for Scaffolds and Falsework. The new standard imposes mandatory regulations on the load transfer efficiency, corrosion resistance, and installation torque of Scaffolding Screwed Coupler.
Key revisions include:
- Increasing the shear strength requirement for right-angle couplers from 12kN to 15kN;
- Introducing dynamic cyclic loading tests (frequency: 1–3Hz) to simulate connection stability under construction vibration;
- Raising the zinc coating thickness standard from ≥85μm to ≥100μm, extending service life to over 20 years in marine climates.
Chinese export enterprises, such as Tianjin Huayou Scaffolding Co., Ltd., have adjusted their production lines to comply with the new standard. Their Hot-Dip Galvanized Coupler has passed EN 74 certification, with torque control accuracy of ±5%, meeting the strict requirements of the European market.

Relevance Analysis
- Technical Synergy: Domestic China’s load adaptation technologies for Q235B Pipe (e.g., wall thickness optimization, thread precision control) complement the EU’s EN 74-1:2025 mechanical requirements for couplers, collectively enhancing the safety of construction support systems.
- Policy Drive: China’s green building materials policy promotes the application of Q235B Pipe in low-carbon construction, while the EU’s standard update forces export enterprises to improve product quality — both reflecting the industry’s shift toward efficiency and sustainability.
- Market Impact: The EU’s new standard may increase the export cost of Chinese scaffolding products by 10%–15%, but it will drive long-term industry upgrading. Domestically, China’s policy is expected to create new demand for Q235B Pipe, with the related market scale projected to exceed RMB 50 billion by 2026.
