1、 Core attributes and customization advantages (OEM core values)
As an OEM customized product, its core advantage lies in "on-demand adaptation", which can achieve full dimensional customization according to specific customer needs, solving the pain points of "functional redundancy" or "insufficient adaptation" of general cabinets. Specific customization directions include:
Size and structure customization: According to the installation site (such as roadside, roof, outside the base station machine room) and internal equipment size, the cabinet height (500-2200mm common range), width, depth, as well as the layout of internal compartments, supports, and cooling channels can be customized, supporting single door, double door, front and rear door and other structural designs.
Interface and hole customization: Based on the cable connection and signal transmission requirements of electrical equipment, precise power interface holes, network cable holes, ventilation holes, etc. can be opened. The size, quantity, and position of the holes can fully match the layout of the equipment interface, avoiding damage to protection caused by secondary holes in the later stage.
Brand and appearance customization: Support printing customer brand logo, product model, warning signs, etc. on the surface of the cabinet. The color can be customized according to the customer's brand VI or outdoor environment (such as anti-corrosion gray, industrial blue) to enhance brand recognition and scene integration.

2、 Core material characteristics (sheet metal material advantages)
The main body of the cabinet is made of sheet metal materials such as cold-rolled steel plate, galvanized steel plate, or stainless steel plate, which are processed through precision processes such as laser cutting, CNC bending, welding, and polishing. It has the dual advantages of "strength" and "protection" and is suitable for complex outdoor environments
High structural strength: The tensile strength of sheet metal material can reach over 345MPa (cold-rolled steel plate standard), and the load-bearing capacity of the cabinet is strong (the top load-bearing capacity is usually ≥ 50kg, and the internal layer board load-bearing capacity is ≥ 30kg), which can resist slight outdoor impacts (such as wind blown debris impact, small falling objects), and is not easily deformed after long-term use.
Corrosion and aging resistance: The surface has undergone multiple anti-corrosion treatments - conventional products use the "acid pickling phosphating+electrostatic spraying" process, with a coating thickness of ≥ 60 μ m and a salt spray resistance test of 48-96 hours (suitable for general outdoor environments); High corrosion scenarios (such as coastal areas and industrial zones) can be upgraded to galvanized steel plates or 304/316 stainless steel materials, with a salt spray resistance test of over 200 hours, effectively resisting erosion from rainwater, moisture, and industrial dust.
High processing accuracy: The sheet metal process can achieve a size error control of ± 0.1mm, and the cabinet splicing gap is ≤ 1mm. This not only improves the flatness of the appearance, but also reduces the infiltration of dust and rainwater through the gap, ensuring the safety of internal equipment.

3、 Core functions and outdoor protection capabilities
The core requirement for outdoor scenes is to "resist the impact of harsh environments on electrical equipment". This cabinet meets industrial grade protection standards through multiple designs, with common protection levels up to IP54-IP65 (customizable). Key functions include:
Waterproof and moisture-proof: The cabinet door adopts a "stepped sealing structure"+EPDM sealing strip (resistant to high and low temperatures -40 ℃~80 ℃), and the top can be optionally equipped with a "sloping top or rainproof cap" to prevent rainwater from seeping into the gaps of the cabinet door; A drainage hole is opened at the bottom to quickly drain even a small amount of water, preventing internal moisture and short circuits.
Dust and foreign matter prevention: The seams of the cabinet are sealed with sealing strips, and the ventilation holes (if any) are equipped with dust-proof nets (which can be disassembled and cleaned regularly). IP65 rated products can completely block dust intrusion and are suitable for dusty environments such as mines and construction sites.
Heat dissipation/insulation adjustment: Customize heat dissipation solutions based on the heat generated by internal equipment - use "natural ventilation holes+heat dissipation louvers" in low heat scenarios; Medium to high heat generation scenarios (such as power equipment) can be equipped with built-in axial fans, heat sinks, or upgraded to "air conditioning heat dissipation modules", with a temperature control range of -20 ℃~55 ℃; Heating plates can be installed in cold regions to prevent internal components from failing due to low temperatures.
Security protection: Standard door lock (optional mechanical lock, electromagnetic lock) to prevent unauthorized personnel from opening; The cabinet grounding terminal (in accordance with GB 7251.1 standard) can effectively export static electricity or leakage current, avoiding electrical accidents; Some customized models can add lightning protection modules to adapt to areas with high thunderstorm incidence.

4、 Applicable scenarios and industry value
With the characteristics of "customization+high protection", this product can accurately match the protection needs of outdoor electrical equipment in multiple industries. Typical application scenarios include:
Power industry: used for outdoor distribution boxes, charging pile control cabinets, protecting power conversion modules and metering equipment, resisting outdoor wind, rain, and sun, and ensuring stable power transmission.
Communication industry: As an outdoor cabinet for 5G base stations, it is necessary to withstand long-term sun and rain exposure and meet the heat dissipation requirements (base station equipment generates high heat) when placing signal transmission and reception equipment and power modules.
Industrial control: Electrical control cabinets used for outdoor production lines in factories, such as sensor signal processing and motor controllers, to resist industrial dust and oil pollution and ensure continuous operation of the production line.
New energy industry: Outdoor combiner boxes and inverter cabinets suitable for photovoltaic power stations and wind power projects, which need to withstand high and low temperatures (-30 ℃~60 ℃), strong ultraviolet radiation, and have anti-corrosion capabilities (some projects are located on plateaus and coastal areas).

5、 Summary of Product Core Competitiveness
Compared to general outdoor cabinets, the core competitiveness of OEM electrical shell sheet metal outdoor cabinets lies in the "three precision":
Accurate matching of requirements: eliminate functional redundancy through OEM mode, retain only the size, interface, and protection level required by customers, and reduce procurement costs and installation difficulties;
Accurate scene adaptation: sheet metal material+customized protective design, capable of handling full scene challenges from "ordinary outdoor" to "high corrosion, high dust, high and low temperature";
Accurate value transmission: supporting brand customization and long-term durability design (with a service life of usually ≥ 8-10 years), it not only enhances the customer's brand image but also reduces maintenance costs in the later stage, making it a "reliable protective barrier" for outdoor electrical equipment.
