How much space are your test weights costing you?
Stackable configurations let you hit exact load requirements without overcomplicating your setup. Lead-filled options reduce footprint. Steel options reduce cost. Both keep your certification process tight.

When elevator systems need to meet new capacity requirements, space becomes the problem.
A major contractor was facing compliance deadlines, but with limited shaft room, traditional steel weights couldn’t deliver the added capacity without exceeding height restrictions.
Mars Metal solved it with custom cast lead elevator weights. By replacing a portion of the existing steel stack with higher-density lead, the required weight was achieved within the same footprint, bringing the system back into compliance on schedule.
If your upgrade is constrained by space, there’s a smarter way to make weight work. See how we did it: https://bit.ly/4av3LpT

Before takeoff, everything is pushed to its limit.
In aerospace testing, weight equals precision. From load shifting simulations to destructive testing, every pound needs to behave exactly as expected.
Mars Metal’s stackable test weights are built for that reality. Consistent, easy to handle, and engineered to meet exact specifications for both destructive and in-flight testing.
When performance is measured in margins, your testing tools can’t introduce variables.
