For functional containers working offshore or in coastal environments, the daily challenge isn’t just waves and wind — it’s the constant presence of salt spray in the air. Chloride ions in salt spray can penetrate coatings and even reach the steel itself, causing corrosion that weakens structural strength and shortens service life. To combat this, TLS has optimized every stage of welding, coating, and corrosion protection so that containers can last longer in harsh marine conditions.

1. Welding – The First Barrier Against Corrosion

Before leaving the factory, every weld is inspected to ensure there are no pores, slag inclusions, or other defects. During welding, TLS minimizes excess spatter and residue — not just for appearance, but to reduce tiny gaps where salt spray could start corrosion. For critical structural points, we use full welding rather than spot welding, which improves strength and reduces stress concentration points.

2. Coating – A Durable Protective Layer

Steel left unprotected near the sea can start rusting within months. TLS uses a multi-stage coating process: first, surfaces are sandblasted to remove scale and oil while creating a rough texture for better adhesion. Next, we apply a zinc-rich primer for cathodic protection, followed by a highly weather-resistant polyurethane topcoat that maintains color and adhesion under UV light and salt spray. Every coating layer meets strict thickness standards so that protection is not compromised by application variations.

3. Corrosion Protection – From Design to Final Details

Corrosion prevention starts at the design stage, not just during painting. TLS adds drainage slopes or holes in areas prone to water collection — such as the container base, door frames, and rainwater channels — to reduce moisture buildup. For bolts, locks, and other fittings, we use stainless steel or hot-dip galvanized materials, and then apply touch-up coatings after installation to avoid weak points.

4. Realistic Service Life Expectations

Under normal use and maintenance, TLS containers can maintain their structure and corrosion protection for around 20 years in a C5-M (marine, very high corrosion) environment. This doesn’t mean the container becomes unusable after 20 years — it means corrosion risks remain controlled and the coating still performs during this period. With lower usage or regular maintenance, lifespan can be even longer.

Conclusion

Salt spray corrosion is a fact of life in coastal and offshore environments, but it doesn’t have to shorten your equipment’s life. With precise welding, advanced coating systems, and thoughtful corrosion prevention in design, TLS ensures every container can perform reliably for years, even in the toughest marine conditions.

In the energy, chemical, and industrial sectors, the stable operation of equipment depends not only on design and manufacturing quality but also on how easy it is to maintain. When customers purchase functional containers, energy storage systems, or explosion-proof equipment, one question comes up again and again: “Will maintenance be difficult later on?”

We understand that complicated wiring, cramped service space, and cumbersome upgrade processes can all increase maintenance costs and risks. That’s why we make “easy maintenance” one of our core design principles—right from the start—optimizing everything from structural layout to reserved interfaces.

1. Easier Wiring

We use separated wiring zones inside and outside the container—high-voltage vs. low-voltage, power vs. communication—to reduce interference and misconnection risks. All cable interfaces are clearly labeled, and quick-release explosion-proof connectors make on-site wiring faster and less labor-intensive.

2. Smarter Access for Servicing

Our internal layout follows an “easy to find, easy to reach” approach—service points are positioned for quick location and direct access. Wide aisles, service doors, and removable panels next to key components mean routine checks and replacements can be done without dismantling large sections, improving efficiency.

3. Flexible Upgrades

We plan ahead for the future, reserving expansion interfaces and mounting points during the design stage. Whether adding fans, replacing controllers, or increasing voltage levels, upgrades can be carried out without large-scale modifications—extending the equipment’s service life.

4. Reducing Maintenance Costs from the Start

These conveniences are not afterthoughts—they’re built into the design from day one. With modular structures, standardized parts, and clear documentation, we help customers keep maintenance effort low and reliability high.

5. Global Service Support

For maintenance needs, we have service hubs in key regions worldwide, equipped with professional teams and spare parts. While coverage is still limited, we are committed to improving response speed to help customers solve problems quickly.

Conclusion

Maintenance should not be a burden—it should be simple and manageable. By making wiring easier, servicing smoother, and upgrades more flexible, we help customers feel confident, comfortable, and in control throughout the entire life cycle of their equipment.

In high-safety applications like functional containers, energy storage units, and pressurized explosion-proof enclosures, structural strength is more than just a number on a blueprint—it’s the key factor that determines whether the equipment can operate safely under extreme conditions. TLS treats Finite Element Analysis (FEA) as a standard step in structural verification, making safety measurable, verifiable, and traceable.

1. Why Structural Strength Matters

Whether facing the wind loads of a category 12 typhoon on an offshore platform or enduring the shocks of lifting during transportation, containers must withstand stress and deformation from multiple directions. If the structure is not strong enough, it may lead to cracked welds at best—or functional failure and serious safety incidents at worst.

2. FEA: Turning Structural Strength from Experience into Data

Traditional structural design often relies heavily on engineer experience, but FEA allows us to create a digital, virtual model to predict risks in advance. At TLS, FEA simulations are performed during the design stage, covering scenarios such as:
  • Lifting conditions: four-corner lifts, two-point lifts, or base lifts
  • Wave impacts: lateral and longitudinal rigidity tests (for offshore use)
  • Wind pressure: especially in high-wind or typhoon-prone areas
  • Transport and stacking loads: structural stability when stacked in multiple layers

With stress maps and deformation analysis, TLS engineers can pinpoint weak areas in the structure and optimize the design before production begins.

3. Data-Driven Improvements

FEA results are not only used to verify designs—they also drive improvements, such as:
  • Adding reinforcement plates at critical points
  • Optimizing weld layouts to reduce stress concentration
  • Increasing rigidity without adding excessive weight

4. From Simulation to Real-World Testing

Simulation is only the first step. TLS validates FEA results with real-world tests such as lifting and load trials, ensuring that “simulated performance = actual performance.”

5. Data for Safety and Future Use

FEA reports and validation records are delivered to clients as part of the technical documentation. This not only proves product safety but also provides a reliable reference for future upgrades or modifications.
By combining digital simulation with real-world verification, TLS ensures every container is engineered for safety—backed by data, tested in reality.
