PC Vertical Architectural

BRS introduction of the PanelCraft 216/218® Standing Seam Roof System in 1996 raised the industry’s benchmark for 2” vertical rib architectural pan panel performance design utilizing Superior Seam TechnologyTM. Since most Vertical Architectural Standing Seam Roof Systems on the market today are adaptions of 1970 technology or even older. 

The design performance criteria for the Metal Standing Seam Roofing System market have substantially changed in the last 50 plus years. 

In response to stricter performance changes BRS, utilizing proprietary Superior Seam Technology™ -SST, designed, developed, tested and deployed the Panel Craft 216/218® Standing Seam Roof System through a network of licensees. The BRS Panel Craft 216/218® Roof System has a performance minded design providing manufacturers an economical solution to meet and/or exceed the higher wind uplift loads, including the stricter edge and corner zones while allowing longer span designs the industry now demands. The ever-changing criterion of the construction industry metal roof code is handled through the many available patented options of the system, such as the panel side joinery, standard clips (fixed or movable), wind clips and numerous accessories such as the High Capacity Rake Plate with up to 7” of travel. The Panel Craft 216/218® vertical rib panel system offers two unique field seaming options: TripleLok® and QuadLok® for maximum performance and design capabilities.

Panel Craft

BRS's PanelCraft Roof System Designed For The 21st Century Consisting Of:

One Panel profile with two seams.

  • TripleLok Seam with higher wind and water performance than double lock panels on the market
  • QuadLok Seam providing high velocity wind performance without the use of external clamps 

Two patented clip options each with increasing uplift ratings.  

Eliminates the need to reduce spans or provide external clamps  

  • 4” Standard
  • 12” wind clip

ASCE 7 divides the roof into multiple zones of uplift load 

  • BRS patented technologies allow for zonal conditions to be addressed by mulitple means (ie zonal seaming and/or multiple clip types)





Consider The Benefits Of Offering Both Seams:

By licensing the PanelCraft system as your standing seam roof, you will have a standing seam roof system with the highest performance of any on the market and be in a position to offer it at a lower cost than other systems.

Some of the High Performance credentials are:

• Florida High Velocity and Broward/Dade County ratings higher than other systems
• Higher ASTM E 1592 loads than others in the industry even those using seam clamps
• Superior weather tightness due to the TripleLok and QuadLok seam configurations

One Panel - Two Seams

The PanelCraft panel is one panel profile that can be installed using one or more of two seams.



Seam 1 - TripleLok™

The TripleLok seam is accomplished with an electric seamer making a single pass at 40 feet per minute. The seamer can seam in both directions (up slope then down slope).

The TripleLok seam is essentially a Double Lock seam rotated 90 degrees, thus reducing prying forces that the double lock seam would receive during uplift loads.

Because of the additional forming, the TripleLok resists separation from the clip much longer than the Double Lock Seam.



Seam 2 - QuadLok™

The QuadLok seam is accomplished with an electric seamer making a single pass along the seam running at 40 feet per minute.

The QuadLok seam is the TripleLok seam rotated down 90 Degrees to further reinforce the seam resistance to unfurling under load.
