A-Frame Glass Racks with safety limit rods

In a busy Glass Factory, gravity is constantly trying to pull your inventory down. All it takes is a forklift bumping a rack, or a worker cutting a strap too early, and a 500kg pack of glass can tip forward.

If you are relying solely on friction or textile straps to hold your glass, you are failing your Risk Assessment. Textile straps wear out. Friction fails when wet. The only true safety is a “Positive Locking” mechanical system. Our Safety-Engineered Glass Racks come equipped with steel Limit Rods that create a physical barrier between your glass and the ground. It’s the difference between a “near miss” and a tragic accident.

The “Second Line of Defense”

Every Safety Officer knows the Swiss Cheese Model of accident causation. You need multiple layers of defense. The angle of the A-Frame is the first layer. The ratchet strap is the second. But what happens if the strap snaps?

That is why we install solid Steel Limit Rods (Safety Bars). These bars insert directly into the structural frame of the rack. They act as a hard stop. Even if the rack is shaken violently or the straps are completely removed, the glass physically cannot fall forward past the rod. This feature is essential for high-traffic areas where workers are constantly walking past loaded racks.

Engineered Stability, Not Just Heavy Steel

Stability isn’t just about weight; it’s about geometry. A top-heavy rack is a ticking time bomb. We design our A-Frames with a wide footprint and a calculated center of gravity that remains low even when fully loaded with Jumbo Sheets.

The base profiles are reinforced Q235 Steel sections, fully welded (not bolted) to the uprights. This rigid triangle structure resists the lateral forces that cause lesser racks to twist and buckle. When you walk through a warehouse equipped with our racks, you see uniform, upright rows—a sign of a controlled and safe industrial environment.

Foundation of safety: A wide, fully welded steel base prevents tipping even under uneven loads.

Protecting Your Most Valuable Asset: Your Team

Glass can be replaced. Your employees cannot. In the UK and EU, liability claims for workplace injuries involving falling objects can bankrupt a small business and bring criminal negligence charges against directors.

investing in certified, safety-equipped racks sends a powerful message to your team: “We care about your life.” It boosts morale and ensures that you pass your HSE (Health and Safety Executive) audits with flying colors. Don’t wait for an accident to upgrade your infrastructure.

Organized Storage = Safer Storage

Chaos breeds danger. When racks are mismatched and overloaded, accidents happen. By standardizing your storage with our modular A-Frame system, you create clear aisles and designated loading zones.

The consistent size and features allow for standardized operating procedures (SOPs). Every worker knows exactly how to secure the load because every rack works the same way. This consistency is the key to building a “Zero Harm” safety culture in your factory.


Frequently Asked Questions

1. Are the limit rods adjustable for different glass thicknesses?

Yes. Our racks feature multiple insertion holes along the base profile. You can position the limit rod snugly against a single sheet or move it out to secure a full pack of 20 sheets.

2. What happens if a forklift hits the rack?

While no rack is indestructible, our fully welded A-frame geometry is designed to absorb impact without collapsing. The wide base helps prevent the entire unit from tipping over during minor collisions.

3. Can I retrofit limit rods to my old racks?

It depends on your existing rack design. However, our rods are designed to work with the specific structural holes in our Mgrack system. For safety reasons, we recommend using the integrated system as a whole.

4. Do you provide load certificates for insurance purposes?

Yes. We can provide technical drawings and load capacity certifications (e.g., SWL – Safe Working Load) for our racks, which you can present to your safety inspectors or insurance auditors.

5. Is the rubber padding fire resistant?

Our standard industrial rubber is heat resistant and durable. While not fireproof, it is designed for industrial environments. For specific high-heat applications near furnaces, we can offer specialized high-temp padding.
