The "Last Mile" of glazing is where 60% of breakage happens. |
When you are delivering to a high-rise project or a commercial glazing site, the environment is hostile. Standard A-frames designed for flat warehouse floors often twist when a forklift hits a pothole, causing stress cracks in the glass. Wooden crates are even worse—they require time-consuming disposal and offer zero structural consistency during crane lifts.
Our heavy-duty L-Shape stillages are engineered specifically for the rigors of construction site delivery. Built from Q235 carbon structural steel with full seam welding (never spot welded), they maintain rigidity even when fully loaded with 4,000 lbs (approx. 1.8 tons) of architectural glass. This rigidity is critical to prevent the "flexing" that leads to spontaneous breakage during transport.
Handling large curtain wall units requires the absolute rigidity of fully welded steel frames.
The biggest bottleneck on a construction site is vertical transport. How do you get a crate of IGUs from the delivery truck to the 15th floor? If your rack isn't crane-ready, you are wasting hours restaging glass.
Our construction site delivery glass stillages come equipped with a dual-handling system:
Four-way forklift entry allows for flexible maneuvering in tight staging areas.
In the glazing industry, we know that "metal on glass" is a death sentence for your product. Vibration during truck transport can cause the glass edge to cut through cheap glued-on rubber pads, leading to catastrophic failure.
We solve this with our proprietary Steel-Core Rubber Profile. Unlike standard rubber strips, our profile contains an internal steel plate and is mechanically fixed to the rack with self-tapping screws. The glass edge cannot slice through this reinforced barrier. Combined with a calculated 3-5° tilt angle, your glass sheets (whether tempered, laminated, or IGU) stay securely nested against the back frame without sliding.
Steel-core rubber profiles prevent the glass edge from contacting the metal frame during transit.
Once the glass is installed, the construction site manager wants your empty racks gone immediately. They take up valuable space. Traditional A-frames are bulky and expensive to ship back to your factory.
Our L-Shape design features a smart Nesting Capability. When empty, the racks slide into one another (like shopping carts) or stack in an inverted L-pattern. This compresses the volume by over 70%. You can fit nearly 100 empty construction site delivery glass stillages into a single truck for the return trip, drastically cutting your reverse logistics costs.
Nesting capability allows for high-density loading, reducing return freight costs.
Q1: Can these racks be lifted by a tower crane while fully loaded with glass?
Yes, the racks are engineered with 4 integrated lifting eyes (pins) specifically for crane operations. However, you must always ensure the glass is secured with proper ratchet straps and the load is balanced before lifting.
Q2: How do you prevent the glass from sliding off during truck braking?
We use a combination of a 3-5° backward tilt design, high-friction EPDM rubber base pads, and dedicated anchor points for ratchet straps. We also offer optional front stop bars (retainer bars) for added security during steep transport.
Q3: Are these racks compatible with Jumbo size glass sheets?
Yes, we manufacture custom sizes. For Jumbo sheets (e.g., 130" x 204" or larger), we reinforce the base and extend the back frame height to ensure full support and prevent the glass from bowing.
Q4: Will the racks rust if left outdoors on a construction site for months?
For long-term outdoor exposure, we recommend our Hot-Dip Galvanized finish. Standard powder coating is durable for normal use, but galvanizing provides a sacrificial zinc layer that prevents rust even if the surface is scratched by site debris.
Q5: Can I mix different glass sizes on one rack?
Yes, but proper loading procedure is critical. Always load the largest sheets against the backrest first, followed by smaller pieces. Ensure the center of gravity remains low and centered to prevent tipping during forklift handling.
