Enclosure walls for steel-structure industrial buildings serve functions such as wind and rain protection, thermal insulation, and general building enclosure; the choice of wall type directly impacts the building's operational performance and lifecycle costs. Understanding the characteristics and suitable applications of these wall types helps in making sound engineering decisions.

I. Profiled Steel Sheet Walls

Profiled steel sheets are widely used as enclosure wall materials for steel-structure industrial buildings; they are manufactured through the cold-forming of color-coated or galvanized steel sheets. They come in various profiles-such as corrugated, trapezoidal, and ribbed-with thicknesses typically ranging from 0.4 to 1.0 mm. Profiled steel sheet walls offer advantages such as light weight, ease of installation, a wide range of colors, and low maintenance costs, making them suitable for industrial buildings with modest thermal insulation requirements. Single-layer profiled steel sheet walls are appropriate for warmer southern regions, whereas cold northern regions should utilize composite assemblies consisting of two layers of sheeting with thermal insulation material sandwiched between them.

II. Sandwich Panel Walls

Sandwich panels consist of two metal face sheets bonded to an insulating core material; they are a common, energy-efficient form of enclosure wall for steel-structure industrial buildings. Core materials may include polyurethane, rock wool, glass wool, or polystyrene, while the face sheets are typically color-coated steel. Polyurethane sandwich panels offer excellent thermal insulation and low thermal conductivity, making them suitable for buildings requiring high levels of thermal performance. Rock wool sandwich panels provide outstanding fire resistance-with fire ratings exceeding one hour-making them ideal for industrial buildings subject to strict fire safety regulations. Sandwich panel walls offer integrated thermal insulation, rapid installation, and a neat appearance, though their initial cost is relatively high.

III. Masonry Infill Walls

Masonry infill walls are constructed using materials such as aerated concrete blocks, lightweight aggregate concrete blocks, or hollow bricks, and are installed within the spaces between the steel frame beams and columns. This type of enclosure wall offers advantages such as readily available materials, low cost, and good sound insulation performance; it is suitable for steel-structure industrial plants with high requirements for thermal insulation and soundproofing. Tie bars should be installed between the masonry infill wall and the steel frame, and a gap should be left between the top of the wall and the underside of the beam-filled with flexible material-to accommodate deformation of the steel structure. Given the significant self-weight of masonry walls, their impact on the primary structure must be considered during design.

IV. Precast Concrete Wall Panels

Precast concrete wall panels are manufactured off-site and transported to the construction site for installation; they fall into two categories: curtain wall panels and composite wall panels. Curtain wall panels serve as non-load-bearing enclosure components and are anchored to the primary structure via connectors, whereas composite wall panels integrate insulation and finish layers, combining the enclosure and thermal insulation functions. These panels offer advantages such as high durability, excellent fire resistance, and low maintenance costs, making them suitable for steel-structure industrial plants where high building quality is required. Installation requires high precision, and the design of connection joints must satisfy requirements for load-bearing capacity and deformation compatibility.
