In big industries like smelting, chemical processing, and mining, the factory roof is facing a tough, ongoing challenge. It’s not just protecting against rain and sun. It’s also enduring a constant attack from high temperatures, harmful acid fumes, and strong UV rays. In these harsh conditions, a normal roofing material doesn’t just fail—it becomes a regular problem for operations.
The most common casualty is painted steel. While cheaper at first, its sprayed-on coating has tiny holes and uneven spots. For a smelter, these small flaws are openings for acidic moisture to begin a continuous process of pitting and corrosion. The result is an expensive cycle of repairs, production downtime, and total roof replacement every few years.
Choosing the right roofing is therefore not just about cost. It is a key decision that affects safety, how well things run, and the company’s finances in the long run. This is why smart industrial managers are moving beyond old materials to a specially designed solution: Jieli’s TSP Film Coated Steel.
The main difference between TSP and painted steel is the way they are protected.
Traditional painted steel uses a coating that is sprayed on. This method, by itself, cannot promise a perfectly smooth, non-porous layer. There are always tiny holes and weak spots. These create places for damaging substances to get through and attack the steel underneath.
However, Jieli’s TSP (Triple-Strength Protection) technology uses a totally different method. We strongly attach a high-performance, modified polyester film directly onto the steel sheet. This film creates a smooth, airtight shield with no pores. There are no tiny holes and no ways for corrosion to start. This process completely seals the steel, offering full protection from the outside world.
Jieli’s TSP Film Coated Steel is designed feature-for-feature to conquer the challenges of the smelting industry.
The airtight polyester film creates a strong barrier against the most harsh industrial chemicals. It is made to stand up to a wide range of acids, alkalis, and salts. Thus, it stops the danger of acidic fumes and salt spray.
Proof in Performance: In a tough 1000-hour salt spray test, our TSP steel showed no rust or damage at all, a result that painted steel just can’t do.
Smelting operations create a lot of heat. Jieli’s TSP sheets are built to work perfectly in steady temperatures ranging from 165°C to 170°C. Unlike other materials that can bend or change shape from the heat, TSP keeps its shape and strength. This makes sure it stays safe and works well for a long time.
The TSP film naturally resists UV rays, preventing the damage that makes normal coatings crack and peel. This airtight seal also offers total waterproofing. As a result, moisture is prevented from ever reaching the steel core, thereby stopping the chemical reactions that lead to rust.
Safety is the top priority. TSP steel is hard to burn and self-extinguishing, achieving a Class-A fire rating. This helps meet strict industrial safety rules and provides important protection for your people and equipment.
While painted steel may seem cheaper at the start, this is a misleading saving. To find the real cost of a roof, you have to look at its whole life.
A painted steel roof in a smelter environment usually needs to be replaced every 2-3 years. A Jieli TSP roof comes with a 15-year warranty.
By choosing TSP, you get rid of the repeated costs of new materials, labor, and—most importantly—time when work has to stop.
The savings from maintenance you no longer need and production that doesn’t stop mean that a Jieli TSP roof typically pays for itself within just 3-5 years. It changes your roof from a constant cost into a reliable, long-term asset.
With over 30 years of experience in making things since 1992, Jieli is a world leader in modern roofing. Our focus on quality is proven by ISO9001:2008 and UL certifications. Our materials are not just tested in a lab. They are proven in some of the toughest industrial places in the world, including demanding mining sites in Chile. We are not just a seller. We are a partner who wants to help your business succeed for years to come.
For smelters and heavy industrial facilities, the choice is simple. Using painted steel roofs that keep failing is not a good plan anymore. Jieli’s TSP Film Coated Steel represents a major improvement, specially made to handle constant heat, acid, and corrosion.
By investing in a TSP roof, you get more than just a better product. What’s more, you get reliable operations, savings over time, and peace of mind for decades.
A: Yes, definitely. The airtight film works very well against damage from salt spray. In fact, its proven resistance to chloride ions, which quickly damage standard steel, makes it a great choice and a highly recommended solution for any industrial facility in a coastal area.
A: While stainless steel handles normal moisture well, it can be unexpectedly damaged by certain strong acids. Jieli’s TSP often provides better protection in these specific high-acid places because its polyester film layer is specifically made for resistance to many different chemicals.
A: Yes. TSP steel can hold a lot of weight and keeps its shape, making it work perfectly with standard long-span industrial truss systems. Unlike some plastic-based roofing that can have problems with expanding or shrinking due to heat, TSP can typically be installed on existing frames without needing changes to the structure.
