What industries does Leka Material serve?

Leka Material serves steel furniture manufacturing, mechanical equipment, fitness equipment, and road traffic facilities industries with specialized powder coating solutions.

What is the difference between smooth and texture powder coating?

Smooth powder coatings (glossy and matte) provide a sleek, even finish ideal for indoor applications, while texture powder coatings (sand grain and wrinkle) offer enhanced durability, scratch resistance, and are suitable for outdoor and high-wear environments.

Powder Coating for Road Traffic Facilities

Road traffic facilities such as guardrails, signs, lighting components, charging equipment and fabricated steel parts require a coating system selected for outdoor exposure, substrate condition and local corrosion risk. LEKA provides customized outdoor powder coatings with project-specific color, gloss and texture options.

The application areas of powder coatings in the field of road transportation facilities are mainly concentrated in road guardrails, bridges and traffic signs, pipelines and ancillary facilities, charging piles, etc. In these fields, powder coatings have demonstrated significant advantages, such as environmental protection, durability, decoration, technical advantages, safety, economic benefits, innovation potential, and market recognition.

Environmental protection
No solvent emissions: Powder coatings do not contain organic solvents and do not produce volatile organic compounds (VOCs), helping to reduce environmental pollution and improve the working environment.
Durability
Wear and scratch resistance: Powder coating can provide a hard coating, enhance the product's resistance to daily use, and extend the life of the equipment.
Chemical resistance and anti-corrosion: Powder coating can effectively prevent product corrosion from sweat, cleaning chemicals, etc., and protect metal surfaces from damage.
Decorative
Color and Texture Diversity: Powder coatings are available in a variety of color and texture options, making the appearance of the product more diverse and attractive.
Beautiful surface effect: Powder coating can form a smooth and uniform coating, improving the market competitiveness and visual appeal of the product.
Technical advantages
Advanced coating technology: Powder coating uses electrostatic spraying technology to ensure coating uniformity on complex-shaped parts and improve coating efficiency and quality.
Curing control: The curing schedule must be matched to the selected product TDS, workpiece thickness and actual metal temperature.
Security
Compliance planning: Regulatory and user-contact requirements should be defined before formulation selection and verified against the agreed product specification.
Stable coating performance: Even under frequent use and harsh environments, powder coatings can maintain stable performance to ensure user safety.
Economic benefits
Reduced Maintenance Costs: Due to the durability of powder coatings, the product requires less maintenance, thereby reducing long-term operating costs.
Improve production efficiency: The rapid curing ability and high powder coating rate of powder coatings reduce production time and material consumption, and improve production efficiency.
Innovation potential
Functional development: With technological advancement, powder coatings are developing more functional features, such as antibacterial, self-cleaning, etc., to meet the specific needs of the market.

Outdoor Coating Guidance for Road Traffic Facilities

Resin system: outdoor-grade weathering polyester is the appropriate starting point for components exposed to sunlight and rain; indoor epoxy or epoxy-polyester powders should not be treated as direct substitutes.
Substrate preparation: steel, galvanized steel and aluminum require a pretreatment process matched to the substrate and corrosion category.
Project specification: define color retention, corrosion testing, film thickness and curing requirements before sample approval.
Customization: RAL colors, customer colors, gloss levels and smooth or textured finishes can be developed for visibility, appearance and maintenance requirements.

Frequently Asked Questions

Which powder coating is recommended for outdoor guardrails and signs?

An outdoor weathering polyester system is normally evaluated first. The final choice depends on the substrate, pretreatment, climate and required test standard.

Can LEKA match an existing traffic-facility color?

Yes. Provide a RAL reference or physical sample, the target gloss and texture, and the intended exposure environment for laboratory matching and spray-panel approval.

Final coating performance depends on the complete system, including substrate, pretreatment, film thickness, curing and service environment. Product selection should be confirmed with the relevant TDS and application testing.
