Storage security seals by American Casting and Manufacturing include but aren't limited to cable, bolt, and padlock seals. The need for security seals is great in the storage industry; companies can rest easy knowing that these options will provide security and peace of mind alike.
Storage security seals range from lightweight plastic pull-tight seals for totes and cartons to heavy-duty bolt seals for outdoor shipping containers and high-value inventory. American Casting and Manufacturing's storage line includes adjustable pull-tight seals, strap seals, padlock seals, bolt seals, and plastic and wire seals, giving warehouse operators a seal matched to every container, door, and opening type across their facility, from storage rooms and cages to gates and yard enclosures.
The primary factors are the container type, the environment, whether indoor or outdoor, and the security level required. For standard warehouse totes and cartons, a lighter pull-tight seal in the 25 to 70 lb breaking strength range is cost-effective and practical at high volume. For outdoor storage containers, intermodal units, or high-value inventory, a heavy-duty bolt seal provides significantly greater physical resistance and requires industrial bolt cutters for removal.
Breaking strengths range from 25 lbs (11.3 kg) on lighter pull-tight models up to 155 lbs on heavy-duty bolt seals. For most warehouse tote and pallet applications, a seal in the 50 to 110 lb range is appropriate. For large outdoor shipping containers or high-value inventory units requiring a high-security closure, the bolt seal is the correct choice and the only one that provides meaningful physical resistance against determined removal.
Yes. Most seals in this line are available barcoded and sequentially numbered. Scanning seal numbers when a container is sealed, relocated, or opened allows warehouse teams to maintain a verifiable electronic audit trail useful for inventory control, 3PL customer audits, and loss-prevention programs. For operations where containers move through multiple dock doors or locations, barcoded seals eliminate the manual scan errors that create gaps in custody records.
A sealed container creates a documented record of every access event. If inventory is short at the time of opening, the seal log shows exactly when the container was last sealed and by whom. This makes it significantly harder for internal theft to go undetected and gives warehouse managers an auditable record to present to customers, insurers, or law enforcement when a loss is discovered. The accountability effect alone deters many opportunistic theft attempts.
For outdoor and cold storage, bolt seals and cable seals with metal components offer better weather resistance than plastic-only models. Heavy duty bolt seals such as the PBLT2 and BLT1-H are well suited for outdoor shipping container doors in exposed environments. For cold-chain storage units, bolt seals are applied to the exterior door hasp and do not contact the stored product directly. For applications where plastic seals are preferred in freezing conditions, AC&M offers several models with a Coldguard additive that reduces brittleness and minimizes breakage at low temperatures. Confirm food-contact compliance for specific models if required by your certifier.
Yes. Custom sequential numbering, company name, color options, and logo printing are available on most seal models. Many 3PL and warehouse operations use color-coded seals to differentiate between customers, product categories, or storage zones, making unauthorized access immediately visible and simplifying the visual inspection process for large facilities with hundreds of sealed units.
Standard stock seals are available in small pack sizes for evaluation or low-volume needs, with volume pricing available for larger orders common in high-throughput warehouse operations. Minimum order quantities for custom-printed seals vary by model. Contact American Casting and Manufacturing at (800) 342-0333 for current stock availability, custom specifications, and volume pricing.
