Engineered Protection for Modern Construction Projects

In today’s construction industry, safety, durability, and long-term performance are critical. Buildings, bridges, industrial complexes, and infrastructure projects are exposed to environmental extremes, fire hazards, and structural corrosion, all of which can compromise their integrity if not properly managed.

At Junhui Technology, we provide advanced fire protection and industrial coating systems designed for the construction sector. Our solutions safeguard steel, concrete, and composite materials, ensuring structural stability, compliance with international fire codes, and reduced maintenance costs throughout the life of a project.


Challenges in the Construction Environment

Construction materials face unique challenges that require specialized coatings:

  1. Fire Hazards: Electrical faults, welding operations, and combustible materials can spark fires in both residential and industrial structures.

  2. Corrosion: Reinforced concrete and steel structures are vulnerable to moisture, salts, and pollutants that accelerate deterioration.

  3. UV Exposure: Exterior facades, bridges, and stadiums face constant sun and weather exposure, leading to fading and surface degradation.

  4. Chemical Exposure: Industrial buildings, parking garages, and infrastructure projects may come in contact with oils, de-icing salts, or cleaning agents that attack coatings.

Junhui Technology’s coatings address all these hazards with engineered fireproofing and corrosion-resistant systems, ensuring long-lasting protection and safety.


Fire Protection Coatings for Construction

Building codes require fire-resistant materials to protect occupants and maintain structural integrity during a fire. Junhui Technology’s intumescent and cementitious coatings provide passive fire protection for steel and concrete structures.

How It Works

When exposed to high temperatures, our intumescent coatings expand to form a dense char layer, insulating structural elements and slowing the heat transfer to the substrate. This delays structural failure, providing critical evacuation time and allowing emergency responders to act.

Applications

  • Steel frames in high-rise buildings: Maintain load-bearing capacity during fire.

  • Bridges and overpasses: Protect critical infrastructure from fire-related collapse.

  • Stairwells, corridors, and escape routes: Ensure safe evacuation paths.

  • Industrial facilities and warehouses: Reduce fire spread in flammable or combustible environments.

Our fireproofing systems comply with UL 1709, ASTM E119, ISO 834, and NFPA 5000 standards, tested for both hydrocarbon and standard building fires.


Industrial Coatings: Protecting Structures from Corrosion and Wear

Construction materials are continuously exposed to environmental and chemical challenges. Junhui Technology provides multi-layer coating systems to protect steel, concrete, and composite surfaces from corrosion, moisture, and mechanical damage.

1. Epoxy Barrier Coatings

High-build epoxy systems provide excellent adhesion, chemical resistance, and impermeability, ideal for structural steel, pipelines, and reinforced concrete. They prevent corrosion caused by moisture, de-icing salts, and industrial pollutants.

2. Polyurethane Topcoats

Polyurethane coatings protect facades, roofs, and exterior steel against UV radiation, weathering, and abrasion. These coatings retain color, gloss, and protective properties even under long-term exposure to sunlight and precipitation.

3. Zinc-Rich Primers

Zinc-rich primers offer cathodic protection for steel frameworks, ensuring the substrate remains protected even if the topcoat is scratched or exposed. Essential for bridges, stadiums, and high-rise construction.

4. Chemical-Resistant Linings

For industrial floors, parking garages, and chemical storage areas, Junhui offers phenolic epoxy and novolac linings that resist acids, alkalis, oils, and cleaning agents, maintaining surface integrity and safety.
