The Metal Frame Medium-High Cabinet is a durable storage or equipment-housing solution characterized by a rigid metal framework (typically steel or aluminum) and paneling (metal, wood, or plastic), designed for medium-high height applications (1.2-2.2 meters) in commercial, industrial, and high-traffic residential spaces. Unlike wooden-framed cabinets (prone to warping, termite damage, or moisture degradation), metal frame models offer superior strength, load capacity, and resistance to environmental stress—making them ideal for server rooms, workshops, garages, and retail stockrooms. The metal frame is the core structural component, providing stability for heavy loads (100-300 kg) and protecting internal contents from impact or damage.

The metal frame’s design and material selection define its performance. Most frames use cold-rolled steel (thickness 1.2-2 mm) for industrial applications—cold rolling increases steel’s tensile strength (up to 500 MPa) and rigidity, enabling the cabinet to support heavy equipment like servers or power tools. Aluminum frames (thickness 1.5-3 mm) are used for lightweight, corrosion-prone environments (e.g., coastal areas or labs with chemical exposure)—aluminum’s natural oxide layer resists rust, and its lower density (2.7 g/cm³ vs. steel’s 7.8 g/cm³) makes the cabinet easier to install. The frame’s structure is typically a rectangular grid: vertical posts (4-6 per cabinet) spaced 300-600 mm apart, horizontal rails (top, bottom, and intermediate shelves) connected via bolts or spot welding, and diagonal braces (for tall cabinets >1.8 meters) to prevent lateral sway.

Paneling and customization options enhance functionality. The cabinet’s sides, back, and doors use panels tailored to the application: galvanized steel panels (for industrial workshops, resistant to scratches and chemicals), stainless steel panels (for food-processing areas, easy to clean and corrosion-resistant), or MDF (medium-density fiberboard) panels with a melamine finish (for office or residential use, offering a wood-like aesthetic). Doors may feature glass inserts (for display purposes, e.g., retail cabinets) or perforated metal (for ventilation, e.g., server cabinets to cool equipment). Shelves are adjustable—mounted on the frame’s vertical posts via clips or bolts—allowing users to modify shelf height (in 25-50 mm increments) to fit items of varying sizes.

Load capacity and safety features are critical for usability. The metal frame’s load rating is specified per shelf and overall: a standard industrial metal frame cabinet can support 50-100 kg per shelf (up to 5 shelves) and 200-300 kg overall. For heavy-duty use (e.g., storing power tools), reinforced frames with thicker steel (2-3 mm) and additional braces can support 150-200 kg per shelf. Safety features include anti-tip brackets (for tall cabinets, preventing tipping if heavy items are placed on top shelves), lockable doors (for secure storage of valuable equipment or hazardous materials), and edge protectors (rubber or plastic strips on frame corners to prevent injury from sharp edges).

Environmental resistance makes metal frame cabinets suitable for harsh conditions. Steel frames are often coated with epoxy powder (thickness 60-100 μm) via electrostatic spraying—this coating resists scratches, chemicals, and moisture, maintaining the cabinet’s appearance for 10+ years. Aluminum frames may be anodized (creating a thicker oxide layer) for enhanced corrosion resistance. For outdoor or humid environments (e.g., garage cabinets), cabinets are sealed with waterproof gaskets around doors and vents to prevent water or dust ingress.

Whether used for server storage in a data center, tool organization in a workshop, or retail display, the Metal Frame Medium-High Cabinet delivers durability, strength, and versatility—outperforming wooden cabinets in high-stress or heavy-load applications.
