OCEAN FREIGHT SOP · AGRACK GLASS STORAGE TRANSPORT RACK
At sea, a glass load can shift before anyone sees the damage. Use the rack’s welded tie-down loops to control movement, and replace a steel-core EPDM strip as soon as its steel core is exposed. These two checks make damage prevention a repeatable operating standard—not a promise of permanent maintenance-free service.
For export glass, the sea leg is not simply a longer truck journey. Vessel motion, braking at the terminal, container handling and road vibration can turn a small clearance into repeated impact. A disposable wooden crate may isolate one shipment, while a fixed steel A-frame may hold the load in one position, but neither automatically solves return logistics. Agrack is relevant when the same vertical glass storage transport rack must support factory staging, containerized transport and empty-rack recovery.
The protection plan has two separate jobs: prevent the glass bundle from moving, and keep every contact surface soft and intact. The first is a lashing SOP. The second is a visual inspection and replacement SOP. Neither should be replaced by a generic assumption that a heavy-duty glass transport rack is automatically safe.
1. How to tie down a glass rack so the load does not shift
Start with the load, rack and container as one restraint system. Before loading, confirm that the rack is fully opened, its folding mechanism is locked, the safety pins are inserted, and the front stop block has not been removed. Place the glass vertically within the designed support area, maintain the specified lean and keep the glass seated against the EPDM-protected contact members. Do not use the lashing loops to compensate for an overloaded rack, an unstable glass bundle or a fork pocket that does not match the handling equipment.
Route rated tie-down straps through the welded steel lashing loops on the base frame, then tension them in a controlled sequence so the bundle is held back against the rack without point-loading the glass edge. Use edge protection wherever a strap could bear on glass or on a sharp metal transition. After tensioning, mark the strap position and record the inspection. Recheck after forklift transfer, after container stuffing and before the container is sealed. On arrival, inspect before releasing the restraints. Agrack’s lashing loops provide defined attachment points; they do not replace a transport engineer’s selection of strap rating, anchor arrangement or container blocking method.
2. When must the EPDM rubber strip be replaced?
Inspect the 10 mm EPDM rubber strips at every loading and unloading cycle, with extra attention after a long sea voyage. The strip is designed with an internal steel plate and is mechanically secured with countersunk self-tapping screws—not bonded with ordinary adhesive. That construction reduces the risk of glue aging or debonding, but it does not make the buffer indestructible. Replace it immediately when the steel core or internal plate is visible, when a cut or tear reaches the contact face, when the strip is peeling or moving, when a screw is missing or cannot hold the strip tight, or when compression has created a hard, uneven contact point.
Do not cover exposed steel with tape, add a new rubber layer over a loose strip, or continue loading valuable Low-E glass while waiting for a later maintenance window. Exposed metal can scratch a coating or glass surface during vibration. Quarantine the rack, photograph the defect, remove the failed section and fit the specified replacement using the mechanical fixing method. Record the rack ID, location, defect and release date. This is a replaceable wear component, not a permanent no-maintenance claim.
3. How the two SOPs work together to drive damage toward near zero
Near-zero damage is an operating target that depends on load design, handling discipline and inspection records. The lashing loop controls relative movement; the EPDM buffer prevents steel-to-glass contact when the rack and load experience vibration. Agrack’s Q235 welded frame, vertical support members and rubber-lined contact zones establish the hardware basis, while hot-dip galvanizing is the more appropriate finish for exposed or humid logistics environments than relying only on an indoor powder-coated surface. Forklift pockets support planned handling, and optional lifting hooks can be specified where a project requires crane transfer; lifting points are not assumed on every rack.
Select Agrack when you need a returnable glass transport pallet that can be loaded at the production line, moved by forklift, secured for sea or road freight, and folded for empty return. A standard reference configuration may use a 1,500 kg dynamic load and 4,500 kg static load, but capacity, rack dimensions, stacking height, fork access and container quantity must be confirmed against the actual glass, equipment and transport plan. It is not the right choice for loads that cannot be safely supported vertically, for uncontrolled mixed cargo, or for a site that will not perform restraint and buffer inspections.
Export loading and maintenance checklist
- Before loading: verify the rack is fully open, safety pins and front stop block are present, the glass lean and capacity match the approved loading plan, and all EPDM contact strips are seated.
- Before sealing: route rated straps through the welded tie-down loops, protect strap edges, confirm even tension and photograph the final restraint arrangement.
- At every handoff: recheck for load movement, loose hardware, damaged straps and any new contact mark after forklift or crane handling; use lifting hooks only when the rack is specified and the lift plan allows it.
- Replace immediately: any EPDM strip with exposed steel core, a torn or displaced contact face, missing fixing screws or hard uneven compression. Never hide the defect with adhesive or an overlay.
