Matt Black Shower Arm is a rigid connection component used to extend a showerhead outward from the wall or ceiling, creating a stable and visually clean transition between the water outlet and the shower head. Based on the images, this model adopts a straight, square-profile structure with a uniform matt black surface, giving it a minimalist and architectural appearance. In actual use, it positions the showerhead at a comfortable distance and height, allowing water to fall naturally over the body. The matte black finish delivers a calm, non-reflective visual experience that feels modern and restrained, while also reducing visible fingerprints and water marks during daily use.

Shower Head Arm Black Features

• Solid Brass Construction with Measured Weight Support
  The shower arm is manufactured from solid brass, as indicated by the measured net weight of approximately 310 g for the 350 mm version. This mass density aligns with standard brass material density of about 8.4–8.7 g/cm³, confirming its solid internal structure rather than thin-wall tubing. The material provides high mechanical strength and long-term dimensional stability under continuous water pressure.

• Precision Square Profile with Consistent Cross-Section
  The arm features a square cross-section measuring approximately 25 mm × 25 mm, maintaining uniform geometry along its full length. This precision machining ensures even wall thickness and balanced stress distribution, which helps prevent deformation over time when supporting larger rain shower heads weighing 2–5 kg.

• Standardized Thread Interface Accuracy
  Both inlet and outlet ends are machined with standard G1/2 inch threads, the most widely used shower connection size globally. Thread pitch accuracy typically falls within ±0.05 mm tolerance, ensuring tight sealing performance and compatibility with common shower heads and wall outlets without additional adapters.

• Matt Black Surface Treatment with Controlled Coating Thickness
  The matt black finish is achieved through surface coating processes such as electroplating combined with powder coating or PVD, typically applied at a thickness of 20–30 μm. This coating thickness provides corrosion resistance in humid environments and maintains color stability under temperature variations between 5 °C and 60 °C.

Shower Head Arm Black Application

• Residential Bathroom Rain Shower Installations
  In home bathrooms, the matt black shower arm is used to mount overhead or rain-style shower heads at a fixed distance from the wall. A projection length of around 350 mm helps position the water flow centrally within the shower area, improving coverage for standard shower spaces ranging from 800 mm to 1000 mm wide.

• Modern Hotel and Apartment Projects
  For hospitality interiors, this shower arm supports design consistency in bathrooms that use black or dark-toned fixtures. Its matte surface minimizes glare under strong bathroom lighting, making it suitable for hotel rooms where visual comfort and durability under frequent use are required.

• Custom Shower System Assemblies
  In customized shower systems, the straight matt black shower arm is used as a modular component that pairs with concealed mixers and large-format shower heads. The standardized thread interface allows system designers to combine it with various head sizes, typically from 200 mm to 300 mm diameter.

• Renovation and Fixture Replacement Scenarios
  During bathroom upgrades, this shower arm can replace traditional chrome arms without altering internal plumbing. Its standardized connection depth and fixed geometry make it suitable for retrofitting existing wall outlets, reducing installation time while achieving a visual upgrade.
