Concrete filled stainless steel columns (CFSSC) combine the advantages of both concrete and stainless steel columns to offer a durable and high load carrying solution. Concrete-filled stainless steel columns are used in many engineering applications including: columns, beams, trusses and many forms of structural components. The stainless steel grades most commonly encountered in construction industry are Austenitic, Duplex/Lean duplex and Ferritic grades. Austenitic stainless steels are generally selected for structural applications which require a combination of good strength, corrosion resistance, formability and weldability. Where higher strength and/or higher levels of corrosion resistance are required, the duplex stainless steels or lean duplex stainless steels, with lower material cost, are most suitable. Ferritic stainless steels, containing no or very low nickel content, provide a cost effective solution to applications where strong and moderately durable structural elements with attractive metallic surface finish are required.

混凝土填充不锈钢柱（CFSSC）联合收割机结合了混凝土柱和不锈钢柱的优点，提供了一种耐用和高承载力的解决方案。混凝土填充不锈钢柱用于许多工程应用，包括：柱，梁，桁架和许多形式的结构部件。建筑行业中最常见的不锈钢牌号是奥氏体、双相/贫双相和铁素体。奥氏体不锈钢通常用于需要良好强度、耐腐蚀性、可成形性和可焊接性的结构应用。在需要更高强度和/或更高水平的耐腐蚀性的情况下，具有较低材料成本的双相不锈钢或贫双相不锈钢是最合适的。铁素体不锈钢不含镍或镍含量极低，为需要具有有吸引力的金属表面光洁度的坚固耐用的结构元件的应用提供了一种具有成本效益的解决方案。
