Why outdoor telecom cabinets demand specialized sheet metal fabrication<\/h2>\n<p>Telecommunications infrastructure increasingly deployed at the network edge, often in locations with no existing shelter. A 5G remote radio unit (RRU) and its associated power supply and fiber distribution equipment must housed in a cabinet that withstands extreme temperature swings from -40\u00b0C to +55\u00b0C, heavy rain, blowing dust, and, in coastal areas, salt-laden fog. A standard NEMA 1 indoor enclosure will fail catastrophically within months under these conditions. Water ingress through a poorly sealed seam or a corroded door hinge will cause condensation, short circuits, and eventual equipment failure.<\/p>\n<p>A <strong>weatherproof sheet metal enclosure<\/strong> fabricated from the appropriate materials, with fully welded seams and high-performance gaskets, is the only viable solution. The enclosure must designed and tested to meet IP65\u2014total protection against dust ingress and protection against low-pressure water jets from any direction. Achieving this rating consistently in volume production requires a manufacturer with deep expertise in precision sheet metal fabrication and a commitment to documented quality processes. TPS Elektronik\u2019s approach to these challenges grounded in its comprehensive <a href=\"https:\/\/tps-elektronik.com\/en\/custom-sheet-metal-fabrication-precision-manufacturing\/\">custom sheet metal fabrication and precision manufacturing<\/a> capabilities.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-14589\" src=\"https:\/\/tps-elektronik.com\/wp-content\/uploads\/2026\/06\/Fiber-Laser-Cutting-Precision-Aluminum-Plate-Electronics-Enclosure-Sheet-Metal-Fabrication-\u2013-TPS-Elektronik-2.jpg\" alt=\"Fiber Laser Cutting Precision Aluminum Plate Electronics Enclosure Sheet Metal Fabrication \u2013 TPS Elektronik Faserlaserschneiden Pr\u00e4zisions-Aluminiumplatte Elektronikgeh\u00e4use Blechfertigung \u2013 TPS Elektronik\" width=\"1920\" height=\"1078\" \/><\/p>\n<\/section>\n<section id=\"en-tps\">\n<h2>2. TPS custom sheet metal fabrication for IP65 enclosures<\/h2>\n<p>TPS Elektronik\u2019s fabrication service for outdoor telecom enclosures is a fully integrated workflow that spans material selection, precision cutting and forming, robotic welding, and advanced surface finishing. By controlling the entire process under one roof, TPS ensures that the final product meets the stringent dimensional and environmental performance requirements of the telecommunications industry.<\/p>\n<h3 id=\"en-material\">2.1 Material selection: galvanized steel and stainless steel<\/h3>\n<p>The choice of base material is the first and most critical decision in fabricating an outdoor enclosure. For the majority of applications, TPS uses hot-dip galvanized steel (typically DC01 or S235JR grades) which provides excellent corrosion resistance through a sacrificial zinc layer. For highly corrosive coastal or industrial environments, TPS fabricates cabinets from grade 304 or 316L stainless steel, which offers inherent corrosion resistance without the need for post-fabrication galvanizing. The sheet metal is sourced with full material traceability, and certificates are provided with every production lot, as detailed in our guide to <a href=\"https:\/\/tps-elektronik.com\/en\/ems-sheet-metal-processing-electronics-enclosures\/\">EMS sheet metal processing for electronics enclosures<\/a>.<\/p>\n<h3 id=\"en-sealing\">2.2 Welding, sealing, and gasketing for IP65 integrity<\/h3>\n<p>The most common point of water ingress in a fabricated enclosure is the seam between two metal panels. To eliminate this vulnerability, TPS employs continuous <a href=\"https:\/\/tps-elektronik.com\/en\/mig-welding-machine-welding\/\">MIG welding<\/a> for all structural seams. As detailed in our comparison of <a href=\"https:\/\/tps-elektronik.com\/en\/mig-vs-tig-welding-key-differences\/\">MIG vs TIG welding<\/a>, MIG is the preferred technique for its speed and deep penetration on heavier gauge steels. After welding, all seams are ground smooth, and a polyurethane or silicone sealant is applied internally to guarantee a watertight barrier. For removable panels and doors, TPS utilizes closed-cell EPDM gaskets that are compressed within a formed channel, creating a reliable compression seal that maintains its elasticity and performance over thousands of opening cycles and across the full operating temperature range.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-15639\" src=\"https:\/\/tps-elektronik.com\/wp-content\/uploads\/2026\/07\/Continuous-MIG-Welding-Outdoor-Telecom-Cabinet-Seam-Weatherproof-IP65-\u2013-TPS-Elektronik-3.jpg\" alt=\"Continuous MIG Welding Outdoor Telecom Cabinet Seam Weatherproof IP65 \u2013 TPS Elektronik Durchgehendes MIG\u2011Schwei\u00dfen Outdoor Telekom\u2011Schranknaht wetterfest IP65 \u2013 TPS Elektronik\" width=\"1920\" height=\"1079\" \/><\/p>\n<h3 id=\"en-finishing\">2.3 Corrosion protection: surface finishing and powder coating<\/h3>\n<p>The external surface finish is the final barrier against the elements. TPS applies a high-performance polyester powder coating over a pre-treated surface. The pre-treatment process, which includes degreasing and phosphatization, ensures maximum adhesion of the powder coat. The polyester powder is specifically chosen for its UV resistance, preventing chalking and color fading over years of direct sunlight. This finish is tested for salt spray resistance, typically exceeding 1,000 hours per ISO\u202f9227, providing robust protection against corrosion.

Compliance and standards: IEC 60529 and ETSI environmental classes<\/h2>\n<p>An IP65 rating is not a suggestion; it is a certified test result defined by <a href=\"https:\/\/webstore.iec.ch\/en\/publication\/26610\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">IEC\u202f60529<\/a>. The &#8220;6&#8221; indicates complete protection against dust ingress (dust\u2011tight), and the &#8220;5&#8221; indicates protection against water jets projected by a nozzle (6.3\u202fmm) against the enclosure from any direction. TPS can provide certified IP65 test reports for its fabricated enclosures, verifying their compliance. For the European telecom market, enclosures are also designed to meet the relevant ETSI environmental classes (such as EN\u202f300\u202f019-1-4 for outdoor non-weather-protected locations), which specify temperature, humidity, and solar radiation requirements. This documented compliance is essential for network operators to qualify the enclosure for deployment and is a standard part of the TPS quality assurance package.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-15629\" src=\"https:\/\/tps-elektronik.com\/wp-content\/uploads\/2026\/07\/IP65-Gasket-Sealing-Telecom-Cabinet-Door-Locking-Handle-Outdoor-\u2013-TPS-Elektronik-5.jpg\" alt=\"IP65 Gasket Sealing Telecom Cabinet Door Locking Handle Outdoor \u2013 TPS Elektronik IP65 Dichtungsabdichtung Telekom\u2011Schrankt\u00fcr Verriegelungsgriff Outdoor \u2013 TPS Elektronik\" width=\"1920\" height=\"1079\" \/><\/p>\n<\/section>\n<section id=\"en-applications\">\n<h2>4.
