钢结构建筑是以钢材构件作为主要承重结构，并通过工厂预制、现场装配等方式完成建设的新型建筑形式，具备施工周期短、空间布局灵活、抗震抗风性能较强、绿色低碳和可回收等特点。金属围护系统则是钢结构建筑的重要组成部分，主要以金属板材为核心材料，形成建筑屋面、墙面等外围护解决方案，承担防水、保温隔热、气密水密、耐火、抗风及耐久维护等功能，广泛应用于工业厂房、物流仓储、公共建筑、数据中心及高端制造等场景。
从市场规模来看，中国钢结构建筑市场已形成较大规模，2025年市场规模约为4,500亿元，预计2030年将接近4,900亿元，其中工业建筑是最主要且增长较快的细分领域。中国工业领域金属围护系统市场同样保持稳定增长，2025年市场规模约为1,500亿元，预计2030年将超过1,800亿元。随着高端制造、人工智能、新能源、物流仓储等下游领域持续扩张，钢结构建筑及金属围护系统市场需求有望进一步释放；同时，东南亚、北非等出海市场也为相关企业提供了新的增长空间。
从竞争格局来看，中国钢结构建筑及金属围护系统市场整体均较为分散，行业内既有具备全国化布局和综合服务能力的大型企业，也有大量依托区域市场及细分场景开展业务的中小型参与者。钢结构建筑市场主要参与企业包括精工钢构、多维联合、巴特勒、美联钢结构、万事达等；金属围护系统市场主要参与企业包括多维联合、精工钢构、万事达、森特股份、宏鑫源、巴特勒等。未来，随着下游客户对产品性能、交付效率、系统集成能力和项目经验要求提升，具备产品体系、设计深化、工程交付和跨区域服务能力的企业有望获得更强竞争优势。
Steel structure buildings refer to a new type of building form that uses steel components as the primary load-bearing structure and is constructed through factory prefabrication and on-site assembly. They are characterized by shorter construction periods, flexible spatial layouts, strong seismic and wind resistance, and green, low-carbon and recyclable attributes. Metal enclosure systems are an important component of steel structure buildings. With metal sheets as the core materials, they form exterior enclosure solutions such as roofs and walls, and provide functions including waterproofing, thermal insulation, air-tightness and water-tightness, fire resistance, wind resistance, and long-term durability and maintenance. They are widely used in industrial plants, logistics warehouses, public buildings, data centers, and high-end manufacturing facilities.
In terms of market size, China’s steel structure building market has reached a substantial scale, with market size reaching around RMB450 billion in 2025 and expected to approach RMB490 billion by 2030. Industrial buildings represent the largest and relatively fast-growing segment. China’s industrial metal enclosure systems market has also maintained steady growth, with market size reaching around RMB150 billion in 2025 and expected to exceed RMB180 billion by 2030. As downstream sectors such as high-end manufacturing, artificial intelligence, new energy, and logistics warehousing continue to expand, demand for steel structure buildings and metal enclosure systems is expected to be further released. Meanwhile, overseas markets such as Southeast Asia and North Africa also provide new growth opportunities for relevant companies.
In terms of competitive landscape, both China’s steel structure building market and metal enclosure systems market remain relatively fragmented, with the participation of large companies with nationwide presence and integrated service capabilities, as well as numerous small and medium-sized players focusing on regional markets and specific application scenarios. Major participants in the steel structure building market include Changjiang & Jinggong Steel Building (Group) Co., Ltd., Duowei Union Group Co., Ltd., Butler, USAS Building System (Shanghai) Co., Ltd., and Wiskind Architectural Steel. Major participants in the metal enclosure systems market include Duowei Union Group Co., Ltd., Changjiang & Jinggong Steel Building (Group) Co., Ltd., Wiskind Architectural Steel, Center International Group Co., Ltd., Headstream, and Butler. Going forward, as downstream customers place higher requirements on product performance, delivery efficiency, system integration capabilities, and project experience, companies with stronger product portfolios, detailed design capabilities, engineering delivery capabilities, and cross-regional service networks are expected to gain stronger competitive advantages.
