Finger rail-specific grooved welding pipe products, capable of processing any slot tube size

### Section 1: Handrail-Specific Grooved Welded Pipe Product Introduction

Material

- **Stainless Steel Material**: Special grooved welded tubes made of stainless steel for handrails possess excellent corrosion resistance, ensuring long-term beauty and structural stability in both indoor and outdoor environments. For instance, the common 304 stainless steel, which contains approximately 18% chromium and 8% - 10% nickel, can effectively resist atmospheric corrosion, moist environment corrosion, and侵蚀 by general chemicals, commonly used for handrails in residential and commercial spaces.

- Carbon Steel Material: Welded pipe with dedicated grooves for carbon steel handrails - strength and pricing. Typically, surface treatments such as galvanizing are applied to enhance corrosion resistance. Suitable for applications where cost sensitivity is high and corrosion resistance requirements are not extreme, such as handrails in some warehouses and industrial buildings.

Shape and Dimensions

- **Common Shapes**: Including round, square, and rectangular basic shapes. Round groove welded tubes have a smooth feel and are typically 30-80mm in diameter, commonly used for stair railings. Square and rectangular groove welded tubes are more regular and have dimensions between 20-60mm for edges or length-width, suitable for baluster railings.

- **Groove Design**: The shapes and sizes of grooves are varied. Some grooves are semi-circular, designed for easy fit with handrail accessories; others are rectangular grooves, typically ranging in depth from 3-10mm and width from 2-8mm, used for installing decorative strips, anti-slip strips for handrails, etc.

### Advantages of Machining Any Slot Tube Size

Customized Services

- **Meet Design Requirements**: Capable of manufacturing various unique sizes and shapes of channel pipes according to different architectural styles and designers' creativity. Whether it's for special-shaped channel pipes needed for retro-style buildings or for the simple lines required by modern minimalist styles, custom production is available.

- **Suited for Special Environments**: For specific environments, such as spiral handrails with unique curvature requirements, we can produce custom-sized slot tubes that precisely match the curvature, ensuring the handrails are both comfortable and safe.

2. Quality and Craftsmanship Assurance

- **Manufacturing**: During the manufacturing of slot tubes in any size, our processing equipment ensures precise dimensions. For instance, by utilizing CNC machining technology, we can control the depth and width of the slots within specified tolerances, guaranteeing the tightness and aesthetics of the handrail installation.

- **Welding Technology**: For grooved welded pipes, the quality of welding is crucial. Professional processing factories use advanced welding techniques, such as TIG welding, to ensure the strength and aesthetics of the welded areas. Post-welding, processes like sanding and polishing are conducted to achieve a smooth surface of the pipe, free of welding defects.
