For industrial facilities, dependable operations through decades of harsh conditions demand the toughest infrastructure. The entrance door used the most on the loading dock of any building, needs to perform for thousands of open/close cycles while also being able to tolerate material handling impacts, weathered conditions and persistent machine vibrations. The most appropriate door for long term service in an industrial environment is clearly the steel sectional door because of its structural strength, relatively low maintenance and resistance to the extremes of industrial conditions. Seppes Door has extensively perfected the steel sectional door design over the decades, creating and manufacturing high performing doors for the most extreme industrial conditions worldwide.
Engineered Strength for Impact Resistance and Structural Integrity
The key to the long-term functioning of any industrial door is the impact-resistance. Our sectional doors feature durable color-coated steel panels guided by heavy-duty galvanized steel tracks. This combination offers outstanding durability against dents, scratches, and accidental bumps from pallet jacks, providing far greater resilience in busy loading docks than lighter metal alternatives. Our unique sectional construction further strengthens of the panels and provides integrity when they encounter an object. These steel sectional doors use only the strongest, corrosion-resistant steel alloys rolled with exact tolerances. The individual panels incorporate steel ribs for rigidity that, though strong, don’t increase weight.
Corrosion Protection for Extended Service Life
Reliability in an industrial door means resisting not just daily wear, but also harsh environmental elements. To guarantee long-term durability, our steel sectional doors feature a multi-layered corrosion protection system. The panels are constructed from high-quality galvanized steel and finished with a robust primer and powder coating to withstand rigorous salt spray conditions. Furthermore, meticulous edge sealing prevents moisture ingress into the core. Equipped with hardware that meets high anti-corrosion ratings—including optional SUS304 stainless steel components—these doors are engineered for seamless operation in aggressive atmospheres, high-humidity zones, and demanding washdown applications.
Low Maintenance Requirements Reducing Operational Costs
In order to facilitate long term industrial usage of the door, it should provide maximum possible in terms of minimizing operational stoppages and frequency of maintenance required. The steel sectional door satisfies all such conditions due to its robust construction and field tested operational mechanism. The tough torsion springs, which counterweight the weight of the door, can withstand cycles for hundred thousand in operation and the steel guide tracks are designed with heavy galvanized construction to reduce the wear and misalignments of the tracks. The segmented door construction system helps in replacing a damaged panel at a relatively low cost and avoiding the huge cost and downtime to replace the entire door.
The Seppes Door provides certain maintenance-friendly provisions like the sealed ball bearings in rollers, hardware parts in corrosion proof material, adjustment facility in an easy reachable location, etc. This helps in a significantly low maintenance cost, reduced stocking of spare parts and low cost in terms of labor required for its maintenance during its life time of operations. The managers of facilities are able to plan and budget with higher accuracy in terms of long term operational costs of their facilities knowing that their steel sectional doors will demand minimal attention and attention from their operational personnel and will run trouble free operation for long periods.
Thermal Performance and Energy Efficiency Over Decades
In addition to long-term robustness the steel sectional door also performs exceptionally well as far as long-term energy savings are concerned. The most economical thermal efficiency in a steel sectional door, with its composite of polystyrene or polyurethane, is found where protection of the core against damage and moisture is assured by the steel skins. This guarantees that thermal performance remains optimal throughout the building’s service life.
Our highly accurate joints with an all-round sealing, of course, remain fully functional at optimum level of insulation as the door is being frequently opened.
A high number of integrated thermal breaks and outstanding sealing solutions of the Seppes Door steel sectional door make sure our product keeps up performance year after year.
