This wall-mounted protective carrier is specifically designed for outdoor/semi-outdoor scenarios. It is made of steel and integrates features of rainproof, dustproof, and corrosion resistance. It can accommodate small-sized electrical/network equipment. The core value lies in saving floor space while resisting outdoor disturbances such as rain erosion, dust accumulation, and ultraviolet exposure, ensuring the stable operation of the equipment in wall-mounted scenarios like beside street lamps, on building exteriors, or on utility poles. It is a "compact protective barrier" for small outdoor devices.

Core Protective Performance: Focusing on Outdoor Rainproof and Durability
1. Rainproof and Dustproof: Blocking Environmental Intrusion
The basic protection level reaches IP65 (completely dustproof + resistant to any direction of high-pressure water spraying), and some high-protective models are upgraded to IP66 (resistant to strong water spraying / heavy rain). Key rainproof designs include: EPDM (Ethylene Propylene Diene Monomer) rubber strips are used at the joint between the cabinet door and the cabinet body; an inclined rain-proof canopy is set at the top to prevent rain from seeping through the cabinet door gaps; a brass waterproof gland is provided at the cable inlet, and after threading the cable, it is tightened to prevent rain from entering along the cable gap.
2. Steel Material Characteristics: Balancing Strength and Corrosion Resistance
The main body is made of cold-rolled steel or stainless steel, suitable for different environmental requirements:
Cold-rolled steel model: The surface is treated with double-layer powder coating (polyester epoxy coating, thickness ≥ 80μm), with a neutral salt spray test duration of over 500 hours, suitable for inland dry outdoor environments, with lower cost and high strength (steel plate thickness 1.2-1.5mm, unaffected by slight impacts and deformation);
Stainless steel model: Mostly 304 stainless steel (316L stainless steel can be selected for coastal areas), with a steel plate thickness of 1.5-2mm, a salt spray test duration of over 1000 hours (316L model reaches 5000 hours), capable of resisting rain and moisture corrosion without relying on coatings, suitable for urban outdoor and semi-outdoor scenarios (such as commercial street WiFi equipment, port monitoring modules protection).
3. Anti-UV and Temperature Humidity Adaptability
The surface of the shell (especially the cold-rolled steel model) is treated with anti-UV coating, which does not fade or crack under long-term exposure to ultraviolet rays (ultraviolet intensity 380-400nm); for outdoor temperature differences of -30℃ to 60℃, low-power scenarios (such as sensors) are naturally cooled through ventilation louvers (with dust-proof nets); for high-power scenarios (such as small switches), an internal built-in cooling fan (starts automatically above 40℃) can be selected to avoid equipment shutdown due to high temperature.
 

Structure and Installation: Adapted to Wall-Hanging Scenario Requirements
1. Compact Size and Internal Layout
Following the "small but excellent" design, the size is mostly 300-800mm wide, 400-1000mm high, and 200-400mm deep, suitable for 19-inch standard equipment or non-standard small modules; a detachable galvanized installation plate (with a load capacity of ≤ 50kg) is provided to support flexible equipment fixation; cable management holes and cable management racks are reserved to avoid messy cables causing maintenance difficulties.
2. Wall-Hanging Installation Design
The back is equipped with reinforced hanging ears (the thickness of the cold-rolled steel model hanging ears is ≥ 2mm, and the stainless steel model is ≥ 1.5mm), which can be directly fixed on the wall, utility poles, or equipment brackets, with an installation height recommended at 1.8-2.5 meters; the hanging ears are reserved with long round holes to facilitate fine adjustment of the installation position and adapt to different wall flatness.
 

Typical Application Scenarios
Outdoor Monitoring and Communication: Install power modules for road surveillance cameras and wireless AP (WiFi equipment), select IP65 cold-rolled steel powder-coated model, suitable for street lamp poles and building exterior wall hanging;
Municipal Facilities: Street lamp control modules, traffic signal distribution units, use IP65 stainless steel model (304 material), resistant to rain and long-term outdoor corrosion; Industrial semi-outdoor: Sensors and frequency converter control boxes on the exterior walls of factory workshops, selected as IP66 cold-rolled steel models, resistant to cleaning water and dust in the workshop;
Commercial support: Power cabinets for commercial street advertising screens, access control boxes for residential areas, use IP65 cold-rolled steel powder-coated models, balancing cost and protection;
Coastal scenarios: Small communication modules and humidity sensors at port and dock areas, selected as IP65 316L stainless steel models, resistant to salt spray corrosion. Summary
The selection of wall-mounted rainproof steel enclosures should closely align with "scene environment - equipment requirements - installation conditions": For inland dry environments, the cold-rolled steel powder-coated model is preferred (with lower cost); for coastal/high-humidity environments, the stainless steel model is selected (with superior durability). The enclosure specifications are determined based on the equipment power and size, while ensuring the IP protection level and installation height are adapted to the actual environment. This allows for the maximum utilization of its "space-saving + strong protection" advantages, ensuring the long-term stable operation of outdoor small equipment.
