Product Overview
The Epoxy Powder Coating Steel Drums manufactured by Wuxi Sifang Youxin Co., Ltd. represent a new generation of environmentally friendly and high-performance industrial packaging solutions. These drums feature a high-strength epoxy powder coating applied through electrostatic spraying and baked at high temperature to form a dense, uniform, and durable protective layer.
Compared with traditional solvent-based coatings, epoxy powder coatings provide superior chemical resistance, mechanical strength, and environmental protection, while eliminating harmful volatile organic compounds (VOCs). The result is a cleaner, stronger, and more sustainable steel drum—ideal for packaging chemicals, lubricants, resins, coatings, adhesives, pharmaceuticals, and other industrial liquids or semi-solids.
Engineered to meet international standards for corrosion resistance, impact durability, and surface purity, these drums are trusted worldwide for safe storage and transport in challenging environments.

Key Product Advantages
1.Excellent Corrosion Resistance
The epoxy powder coating forms a continuous, dense, and chemically stable barrier that effectively prevents corrosion caused by water, acids, alkalis, or solvents.
2.Superior Mechanical Strength
The coating has high adhesion and elasticity, resisting cracking, peeling, and impact damage during handling, stacking, and transportation.
3.Environmentally Friendly Coating Technology
Powder coating is a solvent-free process that emits zero VOCs, eliminating air pollution and ensuring compliance with global environmental standards.
4.High Temperature and Chemical Resistance
The cured epoxy film resists degradation under heat and chemical exposure, maintaining a long service life even under demanding industrial conditions.
5.Smooth and Uniform Surface Finish
The electrostatic powder application achieves uniform coating thickness and smooth appearance, improving product aesthetics and cleanability.
6.Low Maintenance and Cost Efficiency
The hard, durable coating minimizes maintenance and repainting costs, providing an overall longer lifecycle and lower total cost of ownership.
Product Composition and Structure
1.Each Epoxy Powder Coating Steel Drum is precisely manufactured with the following structural components
Drum Body: High-strength cylindrical shell formed from rolled steel sheets, welded and tested for airtightness.
Top & Bottom Ends: Deep-drawn and seam-welded for structural integrity.
Interior Coating: Thermoset epoxy powder applied through electrostatic spraying and cured at 180–220°C, forming a continuous, hard, and chemically inert protective layer.
Exterior Coating: Powder epoxy or water-based enamel finish to resist weathering, oxidation, and UV exposure.
Closures & Fittings:
Open-head drums: Detachable lids with clamp or bolt rings for easy filling and cleaning.
Closed-head drums: Dual threaded bungs (2” & ¾”) with nitrile or EPDM sealing gaskets.
2.Manufacturing Process Steps
Surface Treatment: Degreasing, rust removal, and phosphate-free cleaning.
Electrostatic Spraying: Uniform application of epoxy powder using high-voltage static charge.
Curing: Thermal curing to melt and bond the powder into a solid coating film.
Quality Testing: Adhesion, thickness, impact, and corrosion resistance tests for every batch.
Assembly and Handling
Open-head Drums: Lid secured by a lock ring or bolt clamp for easy opening and re-closing.
Closed-head Drums: Equipped with standard bungs compatible with common filling equipment.
Gaskets: Chemical-resistant and food-safe options available.
Stacking: Designed for safe vertical stacking and mechanical handling with forklifts.
Customization: Logo printing, labeling, and exterior color customization available upon request.
Applications
Epoxy Powder Coating Steel Drums are suitable for a wide range of industries requiring corrosion protection, chemical resistance, and cleanliness, including:
Chemical Industry: Storage of solvents, resins, adhesives, coatings, and catalysts.
Lubricants & Oils: Safe containment for engine oils, greases, and hydraulic fluids.
Paints & Inks: Protection against solvent attack and pigment contamination.
Pharmaceuticals & Fine Chemicals: Secure storage for raw materials and intermediates.
Food Processing: Optional food-safe formulations available for non-reactive food ingredients.
Agriculture & Pesticides: Resistance to active agents and fertilizers.
Their robust structure and inert coating make these drums ideal for both domestic and export use, ensuring product integrity from filling to end use.
Quality Assurance
Each drum undergoes comprehensive quality inspection and testing to ensure superior performance:
Coating Adhesion & Thickness Testing
Chemical Resistance (acid, alkali, solvent) Testing
Salt Spray Corrosion Testing (≥500 hours)
Impact and Drop Tests for structural durability
Leakage and Pressure Testing for sealing integrity
Visual Inspection for surface smoothness and uniformity
All production and inspection processes follow ISO 9001-certified quality management systems, ensuring full traceability and consistent performance.
