In a busy glass fabrication plant, floor space is your most expensive asset. If your WIP (Work-In-Progress) area is clogged with bulky wooden A-frames or makeshift carts, you are strangling your production flow. We replace chaotic storage with high-density, nestable steel systems designed specifically for the journey from the cutting table to the tempering furnace. |
Any production manager in the glass industry knows the pain of the "staging area." You have batches of cut glass waiting for the edging machine, or IGU components waiting for assembly. Traditional A-frames are stable, yes, but they consume massive amounts of square footage even when they are empty.
Furthermore, moving glass between stations (e.g., from the washer to the clean room) requires a glass trolley that is agile, not a clumsy wooden crate that requires a pallet jack and two people to steer. The L-Shape design addresses this by offering a single-sided loading capability that can be pushed up against a wall or aisle, freeing up critical forklift lanes.
Empty racks nest like shopping carts, recovering 70% of your floor space.
The fastest way to kill your profit margin is scratching a soft-coat Low-E sheet or chipping the edge of a polished tempered panel. Generic racks often use cheap rubber strips glued to the steel. After a few weeks of sliding heavy glass (1/2" or 3/4" thick) onto them, the rubber slices open or peels off, leading to catastrophic metal-on-glass contact.
Our L-Shape Glass Holding Rack utilizes a proprietary "Steel-Core Rubber" profile. We don't glue it; we mechanically fasten it with self-tapping screws through the internal steel plate. The glass edge rests on EPDM rubber (Shore A 70-80 hardness), but the internal steel core prevents the glass from slicing through to the rack frame. This is critical for maintaining a "Class A" surface quality during internal transport.
Steel-core rubber profiles protect IGU units and never peel off.
Efficiency dictates that you touch the glass as few times as possible. The Grack system is designed to serve double duty. It acts as a WIP storage unit on the production line, but it is also a certified shipping rack.
Once the Insulated Glass Units (IGUs) are sealed and cured, you don't need to transfer them to a separate shipping crate. You simply strap them down using the integrated anchor hooks, pick up the rack via the 4-way forklift channels or overhead crane lugs, and load it directly onto the delivery truck. This eliminates the "double handling" step where 30% of shop-floor breakage occurs.
Engineered with 4-way forklift channels for seamless factory-to-truck transition.
Storing 10 sheets of 12mm tempered glass requires more than just a welded frame; it requires engineering physics. A common failure in lightweight racks is "bowing" under load, which creates stress points on the glass center, leading to spontaneous breakage.
We utilize Q235 carbon structural steel with a calculated wall thickness (2.5mm - 3.0mm) to ensure zero elastic deformation under loads up to 4,000 lbs. The 90-degree uprights are set at a slight 3-5 degree incline, using gravity to safely nest the sheets against the backboard without excessive pressure.
High-grade powder coating and Q235 steel ensure longevity in humid factory environments.
Q1: Can these racks handle "Jumbo" size sheets (130" x 204")?
A: Standard models are optimized for 96" x 130" stock sheets or standard IGUs. However, we manufacture specific "Jumbo L-Racks" with reinforced bases and extended back supports to handle over-sized architectural glass safely.
Q2: Will the rubber profile damage the Low-E coating on soft-coat glass?
A: No. We use non-marking EPDM rubber. It is chemically stable and does not leave residue or react with silver-based Low-E coatings, ensuring the glass is ready for tempering or IGU assembly without additional washing.
Q3: How many empty racks can I fit in storage?
A: Due to the nesting design, you can stack approximately 7 empty racks in the space of 2 full ones. In a standard 40HQ container or a semi-trailer, we can load up to 98-112 units, drastically reducing return freight costs.
Q4: Can we move these racks with a crane?
A: Yes. Every rack comes standard with 4 welded lifting lugs at the top corners, rated for full load capacity, allowing for safe overhead movement in crowded bays where forklifts cannot operate.
Q5: Do you offer different surface treatments for outdoor storage?
A: Yes. While indoor shop trolleys are usually Powder Coated (Blue RAL 5010), we highly recommend Hot-Dip Galvanizing for racks that will be stored outside or used for site delivery, providing 10+ years of rust protection.
