Where Is an Online Zinc Spray Coating System for Tube Mill Used?
An online zinc spray coating system for tube mills is used in tube manufacturing plants to apply a protective zinc layer to steel tubes continuously as they move along the production line. It is commonly used by manufacturers producing tubes for furniture frames, automotive components, greenhouse structures, playground equipment, parking barriers, railings, and electrical conduits, helping improve corrosion resistance and support efficient in-line coating.
02
Automotive Industry
These tubes are used in car seat frames and other automotive tubular components. Zinc coating provides added corrosion protection for metal parts exposed to moisture and everyday use.
03
Agriculture & Greenhouse Structures
Zinc-coated tubes are suitable for greenhouse frames, nursery structures, and tunnel-type agricultural systems. The protective coating helps reduce rust and withstand outdoor exposure.
04
Children's Play Equipment
Zinc-coated tubes are used in frames and structural components for playground equipment. Their corrosion-resistant surface helps maintain durability in outdoor environments.
05
Garages & Parking Barriers
These tubes are used in garage structures, parking barriers, and related protective installations. Zinc coating helps protect the metal from rust caused by changing weather conditions.
06
Balustrades & Railings
Zinc-coated tubes are used in stair railings, balcony balustrades, and other metal railing systems. The coating helps improve resistance to corrosion in indoor and outdoor applications.
07
Electrical Conduits
Zinc-coated tubes can be used for electrical conduit and tubular protection applications where corrosion resistance is required. Their suitability depends on the applicable electrical and safety standards.
08
Exhaust Systems
Zinc-coated or specially coated tubes may be used in selected exhaust-related applications where the material and coating can withstand operating temperatures. The coating must be chosen according to the exhaust system's temperature and corrosion requirements.

About Online Zinc Spray Coating System for Tube Mill
Looking for an online zinc spray coating system for tube mills at a competitive price? Airo Shot Blast Equipments is a manufacturer, supplier, and exporter of online zinc spray coating systems in Jodhpur, India, designed to restore corrosion protection along the weld seam of steel tubes during continuous, high-speed production. The system applies a bonded, silver-grey zinc layer to help protect the exposed seam from rust without interrupting the tube manufacturing process. Contact us for pricing, technical specifications, and a customized quotation based on your tube mill speed and production requirements.
What Is an Online Zinc Spray Coating System for Tube Mill?
An online zinc spray coating system for tube mill is a thermal spray unit installed directly on the tube mill line. The mill forms flat steel strip into a round tube, and a resistance weld closes the seam. The weld needs high heat, which destroys the zinc or other protective coating on the strip near the seam.
The system's arc spray gun melts zinc wire and sprays it onto that seam while it is still hot. The result is a coating that bonds to the steel and blends into the surrounding tube surface, so the weld line is protected and less visible.
How Does an Online Zinc Spray Coating System Work?
- Strip is formed and welded: the mill shapes the strip into a tube and welds the seam.
- Gun is positioned over the seam: the arc spray gun sits at a set distance from the seam inside an enclosed box.
- Wire is fed: a motor pushes two zinc wires (1.6 or 2 mm) toward the gun tip with accurate speed control.
- Arc melts the zinc: the wires meet at the tip of the gun and melt in an electric arc.
- Air sprays the zinc: compressed air breaks the molten zinc into droplets and blows them onto the seam.
- Zinc bonds and cools: the particles solidify into a dense coating on the hot seam, which helps adhesion.
- Sizing rolls finish the tube: they slightly flatten the sprayed layer, giving a partly shiny look and reducing surface porosity.
- Fume is extracted: dust, fume, and overspray are drawn away through a ventilated enclosure to a dust collector.
Key Features & Benefits
- In-line operation: Coats at full line speed, so there is no extra process step or handling.
- Weld seam protection: Restores corrosion resistance exactly where the weld damaged it.
- Hot-seam bonding: Spraying while the seam is hot improves adhesion and deposit efficiency.
- Seam blending: The coating helps hide the weld line.
- Low running cost: Arc spray is among the most economical thermal spray methods, and zinc wire is inexpensive.
- Controlled spray pattern: A narrow spray width limits overspray and uses zinc efficiently.
- Clean, safe operation: The enclosed box with an industrial dust collector removes fine zinc dust and fume from the work area.
- Formable coating: The sprayed zinc withstands the mill's sizing and shaping operations.
- Custom engineering: Built to fit your mill layout and tube sizes.
Why Spray Zinc on the Weld Seam?
| Without seam coating | With in-line zinc spray |
| Weld seam loses its protective coating | Zinc layer restored on the seam |
| Rust starts first at the weld | Whole tube is protected |
| Visible, uneven weld line | Seam blends in with the tube |
| Higher risk of customer rejection or short life | Better corrosion life |
A thin extra layer of sprayed zinc means a more consistent product for furniture, greenhouse, automotive, and construction customers.
Online Zinc Spray vs Other Methods of Protecting the Weld Seam
| Method | Online zinc arc spray | Pre-galvanised strip only | Hot-dip galvanising after forming |
| Seam protected | Yes | No | Yes |
| In-line with mill | Yes | Not applicable | No, a separate plant |
| Extra handling | None | None | High |
| Investment | Moderate | None | Very high |
| Flexibility | Easy to change coating thickness | Fixed | Fixed |
| Best for | Continuous ERW tube production | Low-cost, low-protection tube | Fixed |
Short answer: Choose an online zinc spray coating system when you make ERW tube on a continuous mill and need the weld seam protected without adding a separate galvanising step.
How to Choose the Right Online Zinc Spray Coating System for a Tube Mill
- Tube size range: diameter and wall thickness, which set the thermal spray gun position and spray width.
- Line speed: higher speed means higher zinc deposition and possibly two guns.
- Zinc coating requirement: weight or thickness per your product specification.
- Space on the mill: the 18 × 8 × 12 ft footprint, or a custom size.
- Utilities: 70 cfm at 80 psi compressed air, plus electric power.
- Dust and fume control: an enclosed box with a suitably sized dust collector.
- Integration: position between the weld station and the sizing rolls.
- Support: installation, commissioning, training, and spares.
