Product Description
120-150T/M Full Automatic Anodizing Production Line for Aluminum Stair Handrails
Overview
This full-automatic aluminum anodizing line is professionally customized for architectural aluminum stair railings, handrails and profile accessories. It adopts standard sulfuric acid anodizing technology to form uniform, dense and weather-resistant oxide films.
The line supports decorative and protective anodizing with adjustable film thickness, stable color consistency and excellent surface smoothness. It fully meets outdoor and indoor building decoration durability standards.
Equipped with precise temperature control, circulating filtration and automatic gantry transmission systems, it ensures batch production stability and low maintenance costs for stair railing mass manufacturing.

Process Flow
- Degreasing & Decontamination: Remove surface oil, dust and impurities to ensure clean base surface of stair railings.
- Alkaline Etching: Eliminate surface oxide layer and burrs to uniform the aluminum substrate texture.
- Neutralizing & Desmutting: Remove black smut and alkaline residue to avoid subsequent surface defects.
- Multi-stage Water Rinsing: Adopt counter-flow rinsing to effectively reduce cross-contamination between processes.
- Sulfuric Acid Anodizing: Form high-adhesion protective oxide film under constant current and temperature.
- Optional Electrolytic Coloring: Realize stable metal color tones such as champagne, bronze and black for decorative demands.
- Pure Water Rinsing: Clean residual acid and dye liquid to guarantee high-purity surface.
- Sealing Treatment: Seal oxide film pores to enhance corrosion resistance and weather resistance.
- Constant Temperature Drying: Uniform drying without water spots to ensure finished surface flatness.
Core Advantages
- Stable Architectural-Grade Quality: Precise constant temperature and current control ensure 10–25 μm uniform film thickness, no color difference or streaks for stair railing batches.
- Excellent Weather & Corrosion Resistance: Standard building anodizing process effectively resists outdoor oxidation, rain erosion and daily abrasion, extending service life of railings.
- Full Automatic Batch Production: Gantry automatic operation reduces manual errors, supports stable monthly output of 120–150 tons, suitable for large-scale engineering orders.
- Low Operation & Maintenance Cost: Equipped with circulating filtration and bath stabilization system, long-term tank liquid reuse reduces material consumption and waste discharge.
- Diversified Decorative Effects: Supports natural finish and multiple electrolytic coloring options to match different architectural decoration styles.

Frequently Asked Questions
Q1: What is the service life of anodized aluminum stair railings?
With 10–25 μm architectural-grade anodized film and standard sealing treatment, the railings can maintain stable appearance and performance for more than 10 years in conventional indoor and outdoor building environments, with strong anti-fading and anti-corrosion capability.
Q2: Why choose full-automatic line for stair railing anodizing?
Aluminum stair railings have high requirements for surface uniformity and color consistency. Full-automatic equipment realizes unified process parameters, avoids manual operation errors, and ensures zero color difference in batch engineering products, meeting large-scale construction order demands.
Q3: Can the line support customized colors and film thickness?
Yes. The film thickness can be adjusted from 10 μm to 25 μm, and it supports natural clear finish and multiple electrolytic color options including champagne, bronze and black, adapting to various architectural decoration design requirements.
Q4: What is the monthly output capacity of the production line?
The standard full-automatic anodizing line achieves a stable monthly production capacity of 120–150 tons for aluminum stair railing profiles, which can meet the mass production needs of medium and large architectural engineering projects.
