| Single-Skin Steel Partition | Profiled or flat galvanized steel sheet fixed to a light-gauge steel frame; the cavity may remain open or receive insulation. | Approximately 0.50–1.20 mm steel sheet | Approximately 50–100 mm | Low to moderate without insulation; improved when mineral wool or glass mineral wool is installed in the cavity. | Non-combustible steel facing; actual fire resistance depends on the complete tested assembly, joints, framing and insulation. | Warehouses, workshops, service areas, plant rooms and basic internal divisions | Impact resistance, corrosion protection, fixing method, panel profile and required access to services |
| Double-Skin Steel Partition | Steel sheets installed on both sides of a galvanized steel stud or track frame, usually with insulation inside the cavity. | Approximately 0.50–1.00 mm per face | Approximately 75–150 mm | Moderate to high, depending on cavity depth, insulation density, joints and surface layers. | Suitable for assemblies requiring enhanced fire and acoustic performance when supported by tested construction details. | Commercial interiors, industrial buildings, technical rooms and high-traffic areas | Stud spacing, board or sheet layout, cavity insulation, deflection head details and door-load requirements |
| Insulated Metal Sandwich Panel Partition | Factory-made metal skins bonded to a rigid or semi-rigid core such as mineral wool, PIR or EPS. | Approximately 0.40–0.80 mm per face | Approximately 40–200 mm | Moderate to high; performance varies significantly with core type, thickness and joint design. | Mineral-wool cores generally provide strong fire performance; polymeric cores require product-specific fire testing and classification. | Cold rooms, food-processing spaces, clean production areas, factories and logistics buildings | Core type, thermal conductivity, hygiene requirements, panel joints, vapor control and cleaning method |
| Metal Stud and Metal Board Partition | Galvanized steel studs and tracks faced with metal-backed boards, steel-faced gypsum boards or other tested lining panels. | Metal facing commonly approximately 0.50–0.80 mm; board thickness varies by system | Approximately 75–200 mm | Moderate to high when multiple layers and cavity insulation are used. | Can achieve rated fire resistance only as part of a tested or engineered wall assembly; galvanized components provide corrosion protection in suitable environments. | Offices, hospitals, schools, corridors, accommodation and service risers | Fire rating, acoustic target, impact class, board layers, service penetrations and finishing requirements |
| Demountable Metal Partition | Factory-finished steel or aluminum panels mounted in reusable tracks, frames or clipped modular grids. | Approximately 0.60–1.20 mm metal face, depending on panel design | Approximately 60–120 mm | Low to moderate; higher performance is available with insulated or double-panel configurations. | Panels can be replaced or relocated; fire performance must be verified for the specific modular system and configuration. | Offices, laboratories, educational buildings and frequently reconfigured workspaces | Relocation frequency, panel access, module size, finish durability, cable management and ceiling connection |
| Hygienic Steel Partition | Continuous or joint-controlled pre-finished galvanized steel or stainless-steel sheets with sealed corners and hygienic trims. | Approximately 0.60–1.50 mm metal sheet | Approximately 60–150 mm | Moderate; acoustic insulation can be added behind the hygienic skin. | Easy to wash when correctly detailed; stainless steel and suitable coated steel offer good resistance to moisture and cleaning chemicals. | Food processing, pharmaceutical production, healthcare, laboratories and commercial kitchens | Surface coating, chemical resistance, joint sealing, wash-down conditions, hygiene certification and drainage details |
| Stainless-Steel Partition | Flat stainless-steel sheets or formed panels fixed to a steel or aluminum support frame, often with sealed joints. | Approximately 0.80–2.00 mm stainless-steel sheet | Approximately 50–150 mm | Low to moderate as a bare skin; higher when combined with a framed, insulated cavity. | Excellent corrosion resistance in many wet or hygienic environments; grade selection should match chloride, chemical and temperature exposure. | Commercial kitchens, hospitals, laboratories, cleanrooms and marine or coastal facilities | Stainless-steel grade, finish, weld quality, galvanic compatibility, cleaning chemicals and impact exposure |
| Perforated Metal Acoustic Partition | Perforated steel or aluminum face panels backed by acoustic fleece, mineral wool or another sound-absorbing layer. | Approximately 0.70–1.50 mm metal sheet | Approximately 50–150 mm | Designed primarily for sound absorption; room reverberation control depends on perforation ratio, backing and installation area. | Metal face is non-combustible, but the backing material and complete assembly require separate fire evaluation. | Open-plan offices, auditoriums, transport facilities, studios and industrial noise-control areas | Perforation pattern, open area, acoustic absorption coefficient, backing material, cleanability and visual design |
| Movable Metal Operable Wall | Hinged or sliding metal-faced modules that can be stacked or repositioned to divide large spaces. | Approximately 0.60–1.20 mm metal face, depending on module construction | Approximately 80–150 mm | Moderate to high when modules include acoustic seals and multilayer internal construction. | Fire performance, smoke control and acoustic ratings are system-specific and depend heavily on seals, tracks and module joints. | Conference centers, hotels, training rooms, exhibition spaces and multipurpose halls | Operating frequency, module weight, floor tolerance, stacking space, acoustic seals and maintenance access |
