With world markets opening and infrastructure needs growing, demands for strong, robust building materials have never been greater. Industrial parks, farm buildings, and coastal facilities all face increasingly aggressive weather patterns that test the limits of standard roofing and walling products.
For years, builders and property owners have been stuck in an expensive cycle of fixing and replacing roofing materials. They fight a constant enemy: corrosion. This powerful force causes standard building materials to wear out too soon.
Modern industrial environments concentrate a host of corrosive agents, each playing a role in the rapid degradation of metal.
The Impact of Humidity and Salinity
In coastal and tropical areas, damp air and salty breezes create perfect conditions for chemical reactions. Salt particles aggressively attack protective layers. This leads to deep pitting and crevice corrosion. These issues can weaken a structure in just a few years.
The Threat of Industrial Pollutants and Acid Rain
Factory zones often have high levels of sulfur and nitrogen gases in the air. These mix with moisture to form acid rain. This rain chemically eats away at standard metal coatings. As a result, the bare steel underneath becomes exposed and weak.
The Damage from UV Radiation and Temperature Extremes
Constant sunlight breaks down organic coatings, reducing their ability to protect. Meanwhile, extreme hot and cold shifts cause stress in materials. This can lead to tiny cracks and material wear over time.
In response to these challenges, the market has offered a range of materials, each with significant compromises.
Color Steel: The Problem of Inevitable Micro-Holes and Coating Failure
Traditional painted or powder-coated steel depends on sprayed-on layers for protection. Even with advanced methods, these layers always have tiny holes and uneven spots.These tiny flaws become gateways for moisture and chemicals, initiating corrosion from within and leading to widespread failure.
Non-Steel Alternatives (UPVC): Sacrificing Strength and Thermal Stability
.Materials like UPVC resist chemicals well. However, they often lack the strength to support large industrial buildings. They also struggle to stay stable under high heat, which is common in factories with intense processes.
Stainless Steel: Failing Under Concentrated Chemical Attack
Though effective against general atmospheric corrosion, most grades of stainless steel are not designed to withstand sustained exposure to the highly concentrated acids, alkalis, and salts found in chemical plants, processing facilities, and mining operations.
Recognizing the market’s need for a no-compromise solution, Jieli has engineered a revolutionary approach that fundamentally changes how steel is protected.
Instead of a temporary surface coating, TSP technology creates a permanent, impenetrable barrier.

What is Film-Coating vs. Traditional Painting?
Unlike painting or spraying, which applies a liquid layer that cures on the surface, our film-coating process permanently bonds a pre-manufactured, high-performance solid film directly to the steel.
The Airtight Seal: How Zero Micro-Holes Delivers Total Protection
This advanced film is engineered to be perfectly uniform and free of any microscopic pores. The result is an airtight, hermetic seal that completely and permanently isolates the steel substrate from its corrosive environment.
This technological leap is the result of years of dedicated research and development.
Our Core Innovation: The Modified Polyester Film
The heart of TSP is a specially formulated modified polyester film, designed to provide extreme chemical inertness and high-temperature stability.
Jieli’s Proprietary Adhesive: A 5-Year R&D Achievement
The key to creating a permanent bond lies in our proprietary adhesive. Developed over five years, this specialized formula ensures that the film and steel act as a single, inseparable composite material, even under extreme stress.
Every claim we make for TSP is substantiated by rigorous, verifiable testing, ensuring it performs not just in the lab, but in the world’s most demanding industrial environments.
TSP offers a level of chemical immunity that traditional coated metals cannot match.
1,000-Hour Salt Spray Resistance:
In a grueling 1,000-hour salt spray test using a 5% NaCl solution—more than 14 times saltier than sea air—TSP sheets showed zero rusting or degradation.
Test Result: Immunity to Strong Acids, Alkalis, and Salts (168-Hour Immersion):
When submerged for 168 hours in highly concentrated solutions of sulfuric acid (H₂SO₄), hydrochloric acid (HCL), sodium hydroxide (NaOH), and other aggressive chemicals, TSP showed no fading, swelling, or separation.
From scorching deserts to industrial ovens, TSP maintains its structural integrity.
Proven Performance from -40°C to 160°C
TSP is engineered to operate flawlessly across a vast temperature range, from deep-freeze conditions to continuous high heat, making it suitable for any climate.
Test Result: Perfect Integrity After 50 Freeze-Thaw Cycles
After 50 cycles of extreme temperature shocks, shifting between 80°C and -40°C, TSP samples exhibited no hollowing, bubbling, peeling, or cracking.
We combined absolute corrosion resistance with the inherent strength of steel.
The Power of a Steel Core: Load-Bearing and Impact Resistance
The steel base provides the strength needed for large industrial roofs and tough wall panels. It resists impacts and supports heavy loads effectively.
Test Result: A5-Rated Adhesion—No Peeling, No Delamination
In strict tests for adhesion, TSP earned the highest A5 rating. This shows the bond between the film and steel is nearly unbreakable, with no peeling or separation.
TSP is engineered not only for durability but also for a safer and more comfortable indoor environment.
A-Grade Fire Rating for Maximum Safety
TSP has achieved a Class A fire rating, meaning it is non-combustible and self-extinguishing, providing a critical safety advantage in high-risk industrial settings.
Proven Sound Insulation (25-30 dB Reduction)
The composite nature of the film-coated steel acts as a dampener, reducing noise from rain and industrial operations by a significant 25-30 decibels.
Thanks to its unique combination of properties, TSP is the ideal material for facilities where other materials fail.
TSP provides unparalleled protection in the most aggressive settings.
Chemical and Processing Plants
Coastal, Marine, and Port Facilities
Agriculture, Livestock, and Aquaculture Farms
Mining, Smelting, and Heavy Industry
It is also the superior choice for any large-scale project where longevity and low maintenance are paramount.
Warehouses and Logistics Centers
Water Treatment and Waste Management Plants
While TSP is a premium product, its true value is revealed through lifecycle cost analysis.
An investment in TSP is an investment in operational continuity and long-term savings.
Eliminating the Cycle of Frequent Repairs and Replacements
By installing a roof and wall system designed to last for decades, you eliminate the recurring material and labor costs associated with replacing failed conventional panels every 2-3 years.
Reducing Operational Downtime and Production Losses
A failed roof leads to costly production shutdowns. With TSP, you protect your operations, your equipment, and your revenue stream.

Q1: What is the best roofing material for a chemical plant?
A: Chemical plants need roofing that resists a wide range of harsh chemicals and fumes. TSP Film-Coated Steel is designed for this. Its seamless, non-porous polyester film creates a strong barrier against acids, alkalis, and pollutants. Its A-Grade fire rating adds vital safety. Unlike stainless steel, which can fail under specific chemical attacks, TSP provides broader, more dependable protection.
Q2: How to stop metal roof corrosion in coastal areas?
A: The most effective way to stop corrosion in coastal areas is to completely isolate the metal from salt and moisture. Traditional coatings fail because they have microscopic pores that allow salt ions to penetrate. TSP Film-Coated Steel solves this by using an airtight, bonded film with zero micro-holes. This technology permanently seals the steel, preventing the electrochemical reactions that cause rust, making it the ideal long-term solution for any building near the sea.
Q3: Is a steel roof a good investment for a factory?
A: A steel roof is an excellent investment for a factory if it is protected from corrosion. A standard painted steel roof can become a liability, requiring frequent repairs and eventual replacement. A TSP Film-Coated Steel roof, however, is a superior long-term investment. It combines the structural strength and load-bearing capacity of steel with permanent corrosion resistance. This eliminates costly downtime, reduces maintenance to near-zero, and is backed by a 15-year warranty, delivering a clear return on investment.
