Why this solution for HVAC & electrical environments
Able Hardware manufactures engineered frames, Gestelle, and brackets that support HVAC and electrical equipment in demanding, vibration-prone environments. Built in China for OEMs and project integrators, our welded steel fabrications combine automatic/robotic MIG repeatability with CNC-machined datums and controlled coatings for reliable installation and long service life. We design for grounding and bonding, airflow, cable management, and serviceability from day one—so your field crews spend less time modifying and more time commissioning.

Typical applications in HVAC & Elektrisch (Rahmen, Gestelle, Klammern, Gehege)
- Compressor/fan skid frames and vibration-isolated bases
- Rooftop/curb brackets and wall/soffit brackets for condensers and AHUs
- Equipment racks for inverters, VFDs, drives, and control panels
- Enclosure frames with hinge/latch interfaces, DIN-rail provisions, and cable pass-throughs
- Panel brackets with masked conductive pads for bonding/ESD and EMI screens when specified
- Service platforms, guard rails, and access frames
Typical size bands run from 500 × 400 × 200 mm up to 2200 × 1200 × 900 mm. Payloads for rack systems are commonly 50–800 kg, with wall/floor/roof mounting patterns developed per project. Vibration and dynamic load notes (compressors, Fans, inverters) are captured during DFM.

Oberflächen & Korrosionsschutz (ISO 12944/ISO 8501) with masked grounds & galvanic control
We select finishes per environment class (ISO 12944) with surface prep to ISO 8501:
- Pulvermantel (typ. Ral, 70–100 µm DFT), E-Coat, Zinkbeschichtung, or industrial paint systems.
- Masked conductive pads retained for bonding/ESD; grommeted pass-throughs to protect insulation.
- Galvanic protection strategies applied for mixed-metal assemblies (z.B., stainless-to-carbon isolation).
- DFT verification to ISO 2808.
Fertigungsoptionen
Automatische/Robotermig (und TIG, wenn angegeben), Vorrichtungen & Vorrichtungen, Wiederholbarkeit
Frames and racks are welded on robotic cells for consistent bead placement and penetration. Stainless or cosmetic seams use TIG. We design custom jigs/fixtures to lock datums and hole groups, enabling repeatability from pilot to wholesale runs. Learn more: Automatic Welding.
Sekundäre Ops: Laserschnitt, biegen, Bearbeitung; PEM hardware, cable management, Beschichtung & Verpackung
Panels and brackets are laser-cut with ventilation/perforation patterns and louvers tuned to airflow requirements. Bending forms brackets with accurate flange angles; CNC machining establishes datum pads/bores and tight PCDs. We insert PEM hardware, provide DIN-rail/panel mounts, cable pass-throughs with grommets, and EMI screens on request. Coatings are applied in-house or audited partners with masked grounds. Export packaging includes pallet/crate or KD/flat-pack with protective wrap, labels, and hardware kits. Sehen: Laser schneiden & CNC-Bearbeitung, und Pulverbeschichtung..

FAQ
What materials do you recommend—steel, rostfrei, oder Aluminium?
Kohlenstoffstahl (Q235/Q355) covers most frames and racks. Wählen 304/316 for corrosive/hygienic settings. Use 6061/6082 aluminum where weight or thermal considerations dominate.
Can you add ventilation cut-outs, louvers, and DIN-rail features?
Ja. We laser-cut perforation/vent patterns, form louvers, and integrate DIN-rail/panel mounts, cable pass-throughs with grommets, and EMI screens if specified.
What tolerances and weld class can you hold?
We build to ISO 13920 B/C and ISO 2768 m/f, mit ISO 5817 class C standard and class B on visible/critical joints. Hole PCDs are typically held to ±0.2–0.5 mm where functional.
How do you handle grounding and masked conductive areas?
We add grounding studs/bonding jumpers and mask coating on designated pads to preserve conductivity for bonding/ESD continuity tests.
Which coating system should I choose for my environment?
We select powder coat, E-Coat, Zinkbeschichtung, or paint to meet ISO 12944 environment classes. DFT is verified per ISO 2808 and galvanic control is applied for mixed metals.
What are your MOQs and typical lead times?
Pilots from 5–20 pcs are common; production scales to wholesale. Lead times run ~2–4 weeks for pilots and 4–6 weeks for production depending on finish and volume.
What do you need to quote?
Send 2D/3D drawings (STEP/DWG), Material, beenden, mounting scheme, target loads, and any standards (z.B., ISO 5817 Klasse, AWS D1.1 reference, IP/NEMA cues).
