Product Description

Produced by electrostatically applying fusion-bonded epoxy powder to cleaned and preheated deformed steel bar, then heat-cured to form a continuous, uniform coating. Features excellent corrosion resistance, strong adhesion, high impact resistance, and good flexibility. Base steel grades: HRB400, HRB400E, HRB500, HRB500E, GR60, B500B. Diameter range: 8mm – 40mm. Standard length: 9m or 12m (custom available). Coating color: green (standard), blue, red, or custom. Coating thickness: 180–300 microns (typical 200–260µm). Coating type: fusion-bonded epoxy (FBE) compliant with ASTM A775, A934, or GB/T 25826. Performance: holiday test (porosity) ≤ 3 holes/m, cathodic disbondment ≤ 4mm, impact resistance ≥ 2.5 J. Rib pattern preserved after coating for concrete bond. Patching material available for field repairs. Custom diameters, lengths, and coating colors available. Meets ASTM A775/A934, EN ISO 14654, or GB/T 25826 standards.

Application description:

Widely used in concrete structures exposed to corrosive environments such as bridge decks, parking garages, coastal buildings, marine structures, water treatment plants, chemical facilities, tunnels, and highway pavements. The epoxy coating provides superior protection against chlorides, salt spray, and chemicals, significantly extending the service life of reinforced concrete in harsh conditions.

Production description

Deformed steel bar is cut to length, then thoroughly cleaned by abrasive blasting to remove mill scale, rust, and contaminants, achieving a near-white metal surface. The bar is induction-heated to 230–260°C, then passed through an electrostatic spray booth where fusion-bonded epoxy powder is applied. The powder melts and flows, forming a uniform coating. The bar then enters a curing oven to complete cross-linking. Cooling is followed by a holiday (porosity) test to detect pinholes. Damaged areas are patched with repair material.

Shipping Packaging

For export, epoxy-coated rebar bundles are wrapped with foam or plastic separators between layers, protected with soft padding, secured with steel straps, and fitted with edge protectors. Packed on ISPM-15 pallets or in wooden crates. Labels include grade, diameter, coating thickness, and heat number for safe sea freight.

Why Choose Us?

1.Factory Strength:Direct manufacturer with integrated abrasive blasting, induction preheating, electrostatic epoxy spraying, and curing lines, ensuring uniform coating thickness (200–260µm), strong adhesion, and consistent quality for diameters 8–40mm.

2.Quality Assurance:Strict control of coating integrity (holiday test ≤3 holes/m), cathodic disbondment (≤4mm), impact resistance (≥2.5J), and flexibility; compliant with ASTM A775/A934, EN ISO 14654, GB/T 25826.

3.Certifications & Reports:Mill test certificates (MTC) with each shipment; third-party inspections (SGS, BV) and holiday test reports (porosity) available upon request.

4.Customization & Service:Wide base steel grades (HRB400–HRB500E, GR60, B500B), diameters 8–40mm, standard or custom lengths, coating colors (green, blue, red, or custom), and field repair patching material supplied with fast lead times.

5.Export Packaging:Foam/plastic interleaving + soft padding + steel strapping + edge protectors + ISPM-15 pallets/wooden crates for safe sea freight and scratch-free, coating-protected delivery.

FAQ

1. How to handle epoxy-coated rebar on site to avoid coating damage?

Use padded slings and rubber-coated rollers when lifting. Avoid dragging bars across each other or over hard surfaces. Use plastic-tipped or wrapped tools for cutting and bending. Patch any coating damage (scratches, cuts) immediately with approved epoxy repair material before concrete placement.

2. Can epoxy-coated rebar be welded?

Welding is not recommended because heat destroys the epoxy coating around the weld zone, exposing bare steel to corrosion. If welding is unavoidable, remove the coating at least 50mm from the weld area, weld using low-hydrogen procedures, and re-apply epoxy repair coating after welding.

3. How does epoxy-coated rebar compare to galvanized rebar for corrosion protection?

Epoxy coating provides a continuous barrier against chlorides and chemicals, typically offering better corrosion resistance in severe marine or deicing salt environments. Galvanized rebar relies on zinc sacrificial protection; it is more durable against mechanical damage but less resistant to high chloride concentrations. Epoxy-coated rebar is more commonly specified for bridge decks and coastal structures.
