TRESPA PANEL Joint System – Custom – Wall Joint

Project specific custom design expansion join systems offer a wide range of options to make the elevations more architecturally appealing.

Use of magnets provide additional wind load support for wider seismic expansion joint covers.

Wall finish panels on Exterior / Interior walls can be installed on top of metal joint cover system making the expansion joint cover hidden.

Floor – Heavy Duty – Auto H2O

Heavy Duty Floor Joints

M.H. Powell & Co., Inc. provides a series of seismic expanion joint covers to meet auto load and impacts. These heavy duty floor joint systems are designed to match most structural and design intent.

Due to auto traffic and constant heavy impact, the PTHD, PTHDXW, PTHDS, HDCIP and HDEXW models are incorporated with cast in place anchors which allow proper placement in post tension concrete floor systems

This adjustable anchoring system requires project field coordination for proper installation.

Expand-o-Flash

Expand-o-Flash

Expand-O-Flash joint covers are designed to manage seismic movements of roof joints. These systems are applicable to both new and existing roof conditions as well as related exterior walls. Each cover is a combination of flexible Elastromeric membrane, supported by a closed cell foam,forming a flexible bellow with two metal flanges. Expand-o-Flash system covers are flexible, waterproof and provide ease of installation. Refer Johns Manville Roofing Systems Group for more information www.jm.com

Metal Flanges are available in:

  • 26 GA Galvanized steel
  • Mill Finish Aluminium (0.032″)
  • Stainless Steel (0.081″)
  • Copper (16 oz)
*Alternative materials available upon request
