How to choose a suitable stainless steel outdoor cabinet customization manufacturer?
Choosing a customized manufacturer of stainless steel outdoor cabinets, the core of which is compliance with qualification, excellent technology, matching demand and adequate service, can be directly used for bidding, type selection and factory inspection according to the following 10 dimensions.
I. Basic Qualification and Compliance
Necessary qualification
Business license, general taxpayer qualification ISO9001 quality management system certification ()
Industry-related: CE, RoHS, IP protection level test report, 3C (if applicable)
Original material certificate of stainless steel+third party test report (304/316 composition)
Second, the process and equipment capabilities (core hard power)
process equipment
Laser cutting machine (accuracy ±0.1mm), numerical control bending machine, shearing machine.
Argon welding machine, grinding and polishing, surface treatment line
Have IP55/IP65 sealing test capability.
Key technology
Plate: integral bending is preferred, and flat-fell seams are reduced.
Welding: full welding+grinding and polishing, without virtual welding, missing welding and deformation.
Sealing: EPDM sealing strip, waterproof glue, waterproof joint (glen head)
Surface: wire drawing/sanding/sandblasting, outdoor wire drawing is preferred.
Non-standard customization ability
Can be customized according to drawings/requirements, such as special-shaped, double-layer, with heat dissipation/temperature control/lightning protection.
Can provide structural design, opening and internal layout optimization scheme.
Third, the material control (anti-Jerry-building)
Specific requirements: 304/316 stainless steel, rejected 201/202.
Plate thickness: box body ≥1.2mm, door panel ≥1.5mm, bearing cabinet ≥ 1.5–2.0 mm.
It is required to provide a material warranty commitment, and the compensation for material nonconformity is stipulated in the contract.
Four, project experience and case (the most intuitive reference)
Manufacturers with outdoor cabinets, communication/power/environmental protection/monitoring cases in the same industry are preferred.
Requirements: project list, customer name, site photos and acceptance report.
Focus on: successful cases of coastal/high salt fog/heavily polluted environment (316 material)
V. Production and delivery capacity
Regular nonstandard period: 20–35 days; Complex customization: 45–60 days
Have the ability of small batch trial production and proofing (it is recommended to confirm the proofing first)
Have a stable supply chain, do not rely on outsourcing, and avoid quality and delivery out of control.
Six, internal configuration and detail control
Interior: galvanized/stainless steel mounting plate, guide rail, grounding column and trunking.
Door lock: stainless steel three-point lock/anti-theft lock; Hinge: thickened load-bearing section
Heat dissipation: louver+dust screen, fan, heat exchanger (as required)
Incoming and outgoing lines: waterproof glen head and sealing apron.
VII. Quotation and Cost (Rejecting the Low Price Trap)
Quotation details: material, thickness, technology, accessories, surface treatment, transportation, installation and quality assurance.
Beware: the quotation is lower than the market price by more than 20% (high probability of stealing materials/reducing technology)
In the long run: 304/316+has good technology, long service life, low maintenance cost and higher cost performance.
VIII. Service system (whole process guarantee)
pre-sales
Technical docking: provide scheme design, size check and protection grade matching.
Free proofing: Confirm appearance, seal, size and material.
On sale
Progress feedback: notification of production, quality inspection and delivery nodes.
Can be supervised in factory (important project)
after service
Warranty: 1-3 years (box structure, sealing and welding)
Response: 24-hour technical support and 48-hour on-site service (nearby)
Provide: installation instruction, maintenance manual and list of wearing parts.
