Window Weights
Mars Metal provides a wide range of cast or extruded lead window weights, designed to facilitate the balancing of window sashes. Window Weights are available in round, square or rectangular sections in various desirable lengths with or without center holes. The standard center hole size is one-half inch which allows for the use of rope or chain. The variety of sizes we offer provides the flexibility in ensuring the optimal balance is met.
Weights for windows can be stacked to provide more or less weight until the precise balanced point is achieved. Lead counterweights, unlike steel weights, can be easily cut on site if required. All off-cuts can be reused for other weights.
Lead window weights are becoming the choice by many contractors over steel cast weights due to the space savings obtained, approximately 30% smaller than steel with lead being non rusting.
Most common window weight sizes complete with a half-inch hole through center:
2" in diameter x 5" long = 5.5 lbs.
2" in diameter x 21" long = 21 lbs.
Counterweights
The major portion of our business is lowering the center of gravity in lift equipment and sailboats. For sailboats, we custom design and cast a counterweight called a keel to keep them upright under loading from the wind. For the heavy equipment industry, we design and fabricate counterweights that keep lifting equipment upright when loaded. These two businesses share remarkable similarities, though the in-service use of these products is very different. We believe that the crossing over of the technologies we use benefits all of our customers.
Could you benefit from the Lead Solution?
- What if you could extend your unit's lifting capacity or reach specifications?
- What if you could reduce the size of the weight?
- What if you could reengineer the heavier frames and other costly design compromises?
- What if you could shorten the wheel base to provide improved turning radius and reduced rear end swing?
We develop strategies with our customers in order to provide counterweights that exactly address their needs. This includes tight weight tolerances, rigid adherence to specifications, and a final finish that reflects close attention to detail. We strive to satisfy our customer's design teams, manufacturing groups, cost accountants, and marketing departments.
Test Weights
Our standard test units consist of a two wheeled cart with a lead filled box (approximately 12" square) or an open top box with individual plates that can be easily removed. Each 500-lb cart is mounted to an independent axle with rubber wheels for easy maneuverability. Painted matte black with the capacity stamped onto box, all carts are designed to nest for space savings.
In addition to providing standard weights, Mars Metal engineers, designs and custom builds weights for any test application, from aerospace structural design and taxiway testing to bridge, crane and forklift counterweight boxes. We look forward to the opportunity to design the simplest, most cost effective lead weight solution for your testing needs.
For 25 years, Mars Metal has taken the lead by providing dynamic solutions for many diverse industries. Crafted with precision and care, Mars Metal is the lead source.
