Metal Stretcher Leveling Services

Stretcher Leveling uses a series of E-Drive Levelers to flatten and reduce the crossbow (curvature) before it continues to the stretcher. At the stretcher, clamps grab 40 feet of material and apply 2 million pounds of force, uniformly stretching the material past its yield point. Stretcher leveling can remove all internal stress, eliminating the risk of post-cutting spring back, unlike temper passing.

Temper Passing is the process of squeezing out the stress between two rolling pins, leaving the steelwork hardened.

Temper Passing can't always eliminate internal trapped stress and, if improperly processed, can leave your material "potato chipped" (bowed), leaving you with material that cannot be fabricated. 

We are excited to offer our customers the ability to achieve laser flat sheets with Alliance quality and service behind it.

Applications requiring sheet metal cut to strict dimensional tolerances or with small heat-affected zones for future processes can benefit from Alliance Fabrication and Manufacturing's sheet metal laser cutting services. 

Our state-of-the-art laser systems enable us to cut material thicknesses ranging from .0299" – 1.00”. In addition, our fiber lasers deliver a minimal cutting kerf, thus maximizing cutting precision and accuracy. The result is that each laser provides enhanced cut quality and efficiency while providing a tight tolerance product.

Capabilities:

• 60" x 120" Sheet Capacity
• .0299" - 1.00" Mild steel
• Assisted Gases: Nitrogen, Oxygen, Mix
