IT Industrial safety fence | Alfence
軽量で耐食性に優れた機械ガード用モジュール式安全フェンス
When a welded steel fence makes installation heavy and risky, Alfence modular safety fence uses lightweight aluminum profiles for machine guarding in production plants, cleanrooms, food and beverage areas, pharmaceutical facilities, and other corrosion-sensitive environments. The result is easier manual handling, lower floor loading, and a reconfigurable perimeter guarding system.
Why replace heavy steel with an aluminum profile safety fence?
A welded steel fence or steel mesh guarding system can protect a machine, but each panel and post adds handling weight. On retrofit projects, installers may need lifting equipment and several people to position components, increasing lifting-related exposure, installation time, and floor or mezzanine load. Painted steel can also become a maintenance concern where regular washdown, humidity, or clean production requirements make corrosion and particle control important.
| プロジェクト要件 | Alfence modular safety fence response |
|---|---|
| Reduce manual handling risk | 4040B aluminum posts are 1.8 kg/m and 4040P posts are 2.0 kg/m, supporting manual carrying and upright installation without routine lifting equipment for these profiles. |
| Reduce floor or slab loading | Aluminum alloy profiles reduce the mass of the post-and-panel system compared with a heavy welded steel fence; the final floor anchoring and load check remains project-specific. |
| Adapt to line changes | T-slot aluminum posts, removable panels, and bolt-free panel swap support reconfigurable machine guarding and retrofit guarding. |
| Control corrosion in demanding areas | Corrosion-resistant aluminum and powder-coated aluminum options suit indoor plant installation; outdoor use and washdown duty should be specified with the required surface treatment and environment review. |
| Maintain a safe separation | Steel wire mesh panels, transparent panels, or polycarbonate panels can be selected for perimeter guarding, with layout checks for the required safety distance such as the 120 mm application reference in EN ISO 13857. |
Structure and visual evidence for safer installation
Lightweight aluminum posts reduce the installation burden
Alfence uses an aluminum extrusion frame rather than relying on heavy welded steel sections. The stated 4040B and 4040P weights—1.8 kg/m and 2.0 kg/m—make individual posts easier to carry, align, and fix with a foot connector and expansion bolt. This supports a faster modular installation, reduces the need for multi-person lifting coordination, and helps limit added load on floors and elevated slabs.
Extruded profiles and replaceable panels support reconfiguration
The modular frame combines T-slot aluminum posts with a post-and-panel system. Welded wire mesh provides a visible physical barrier for robot cells, conveyors, AGV paths, CNC machine guarding, and packaging lines; transparent or polycarbonate panels can be selected when visibility or arc-flash screening is part of the application. Removable and reconfigurable panels allow a retrofit guarding layout to change with the production line instead of rebuilding the complete fence.
Material selection for corrosion-sensitive production areas
Food and beverage, pharmaceutical, cleanroom, and selected outdoor projects need more than a generic steel mesh guarding specification. Aluminum profiles avoid the exposed painted-steel rust problem and can be configured with powder coating, welded wire mesh, transparent panels, or other application-specific infill. For washdown, cleanliness, and outdoor exposure, confirm the coating, drainage, cleaning chemicals, temperature, and corrosion requirements before finalizing the bill of materials.
Where this modular safety fence fits
- Robot cell guarding: isolate robotic workstations, welding cells, palletizers, and material-handling equipment while keeping the operating area visible.
- Conveyor and AGV path guarding: separate automated warehouse guarding, conveyor routes, shuttle car protection, and storage zones from pedestrian access.
- CNC and machine tool guarding: use a modular frame for machine perimeter guarding, access doors, safety interlock switches, or safety light curtains.
- Cleanroom and controlled production areas: review the infill, coating, cleanability, and installation details for pharmaceutical, food and beverage, and clean production environments.
- Retrofit guarding: replace an old welded steel fence with reusable components that can be relocated or reconfigured when the line changes.
For each project, confirm the hazard distance, door function, floor condition, impact exposure, and required surface treatment. Alfence supports a practical aluminum vs. steel machine guard comparison: lower component mass and modular rebuilding address installation risk, while the final guarding design must still be verified against the machinery risk assessment and applicable requirements.
Specify the evidence before ordering
Share the guarded equipment footprint, required fence height and width, access-door positions, floor or slab condition, cleaning and corrosion environment, and whether mesh, polycarbonate, acrylic, or tinted panels are required. Typical Alfence references include 40×40 mm or 45×45 mm posts, 20×100 mm mesh, 1000/1800/2000 mm panel heights, 200–1200 mm panel widths, and single or double sliding safety doors subject to the project design. SGF can then confirm the suitable profile, infill, anchoring, and safety accessory configuration.
Move from heavy steel handling to modular safety fence installation
Tell us where the fence will be installed and what the old steel solution is causing—lifting risk, floor loading, corrosion, or difficult line changes. We will review the application and develop an Alfence modular machine guarding layout around the actual equipment and environment.
