Corner Seals

Small gaps, big impact: Corner seals as the decisive finishing touch

At loading docks, seemingly minor yet critical weak points often emerge—particularly in the lower area of door seals, where uneven vehicle floors, varying loading heights, or slight misalignments can create open gaps. This is precisely where corner seals come into play: as a targeted, compact solution that thoughtfully completes your dock sealing concept.

As an experienced partner for safety and efficiency in industrial environments, we supply and install high-quality corner seals that integrate seamlessly into existing door sealing systems. We advise you impartially, source reliable components, and, if required, ensure professional installation—delivering a fully sealed system that truly performs.

Targeted Reduction of Energy Loss

Even small openings at the lower corners can accumulate significant costs over time—through escaping warm air in winter or incoming heat in summer. Corner seals help minimize these leaks, directly improving your facility’s energy balance and supporting stable, consistent indoor climate conditions—even at sensitive workstations directly at the loading dock.

Eliminating Drafts and Suction Effects

When a truck docks, unintended air currents may occur—especially if the seal does not close completely. Corner seals help reduce this “suction effect,” enabling more stable pressure equalization and shielding employees from drafts—a clear benefit for ergonomics and well-being.

Holistic Improvement of Sealing Performance

While door seals often provide good coverage in the middle and upper sections, the lower corners remain a challenge. Corner seals are specifically engineered for these problem zones, reliably sealing hard-to-reach areas—without requiring costly structural modifications.

Flexible Application & Compatibility

Our corner seals are designed to adapt to various vehicle types, dock levelers, and building configurations. They are compatible with common door sealing systems—whether installed on the sides or at the bottom—making them a practical retrofit solution at any time.

Protection Against Weather & Contaminants

Beyond energy efficiency, corner seals also provide practical protection: they prevent rain, snow, dust, or debris from entering the gap between the truck and the building. This not only safeguards your goods, but also protects the floor and reduces cleaning and maintenance efforts.

We see ourselves as your trusted partner for all loading dock needs—not only for lighting or signal systems, but also for sealing solutions.

Together, we analyze your current setup:

• Where do recurring gaps occur?
• Which vehicles dock regularly?
• Is retrofitting feasible—or is new installation more advisable?

Based on this, we recommend suitable corner seals from our portfolio, deliver them promptly, and—if desired—perform professional on-site installation, including integration with your existing door sealing system.

Our goal is not merely a single product, but a well-conceived overall concept: corner seals, door seals, dock lights, and traffic lights ideally working hand-in-hand to create a loading area that is safe, energy-efficient, comfortable, and cost-effective in daily operation.

We’re happy to provide you with a no-obligation consultation—by phone, email, or during an on-site visit. With practical solutions, transparent information, and fair terms.
