Heavy-Duty Welded Steel AC Wall Mount Bracket for Mini Split Outdoor Unit 180-200 Kg Per Pair

Product Description

Definition:

The STW Series is a compact one-piece welded wall-mount bracket designed for split air-conditioner outdoor condensing units. Manufactured from powder-coated cold-rolled steel, the bracket combines a reinforced bent-edge profile with adjustable horizontal mounting slots and multiple wall-side fixing holes. Three standard sizes are available for outdoor units ranging from 9,000 to 36,000 BTU, with model-specific load capacities of 180 to 200 kg per pair.

Surface Protection:

To ensure long-term durability in harsh outdoor environments, the STW bracket is treated with a high-performance Powder Coating finish.

UV Resistance: The coating is specifically formulated to be UV resistant, preventing fading, cracking, or chalking under prolonged exposure to direct sunlight.
Corrosion Resistance: The standard RAL 9003 (Signal White) finish acts as a protective barrier against moisture, oxidation, and industrial pollutants, significantly extending the service life of the support system.

Primary Application

Designed as a universal support solution for the HVAC industry, the STW Welded Bracket is optimized for Wall-Mounted Outdoor Air Conditioning Units. heavy loads and suppress operational vibrations.

Installation Precautions

Load Verification: Ensure the AC unit's weight matches the specific model's capacity (e.g., 180kg for STW-1, 200kg for STW-2/3).
Wall Suitability: Installation should be performed on solid concrete or masonry walls. For hollow-brick walls, specialized heavy-duty fixings are required to ensure safety.
Precision Leveling: Take advantage of the Vertical and Horizontal Mounting Hole design. The elongated slots allow for fine-tuned adjustments to ensure the unit is perfectly level, which is critical for proper drainage and compressor longevity.
Fastener Security: Always use high-quality expansion bolts and ensure they are tightened to the recommended torque. Using vibration-damping rubber pads (if applicable) is recommended to further reduce noise transmission into the building.

FAQ

Q1: What is the maximum load capacity?

  The STW Series supports 180 to 200 kg per pair, depending on the selected model. Actual allowable load also depends on the wall substrate, anchors and installation method.

Q2: Which model should I choose?

  Select the bracket according to the outdoor unit dimensions, base-foot spacing, equipment weight and cooling capacity. Please confirm both bracket dimensions and mounting-hole positions before ordering.

Q3: Is the bracket supplied as a pair?

  Confirm according to actual packaging. The product should clearly state whether one set includes two complete wall brackets.

Q4: Are mounting accessories included?

  Outdoor-unit mounting hardware and wall anchors should be listed separately because accessory configurations may vary by order and wall type.

Q5:Can the color be customized?

  RAL 9003 white is the standard option. Other RAL colors, labels and packaging can be customized subject to MOQ.

Q6:Is it suitable for coastal installations?

  Standard powder-coated steel is intended for general outdoor environments. For coastal or highly corrosive areas, enhanced coating or stainless-steel options should be evaluated separately.
