TS-324 Roof Panel: Trapezoidal Standing Seam Roofing
The BRS TS-324® Standing Seam Roof System is a trapezoidal roof panel system featuring proprietary Superior Seam Technology®, available through a network of BRS licensees.
In 1999, BRS raised the industry’s benchmark again with the introduction of TS-324, building on the overwhelming success of the PanelCraft 216/218® roof systems and their use of Superior Seam Technology™.
Many standing seam roof technologies remain adaptations of designs developed in the 1970s. Yet performance requirements for metal standing seam roofing have changed substantially over the past 50 years, with higher wind and uplift loads, stricter requirements at roof edges and corners, and growing demand for longer spans.
BRS designed, developed, and tested TS-324 in response to these changing requirements. The system gives manufacturers an economical solution to meet or exceed higher wind and uplift load requirements while supporting the longer spans today’s industry demands.
A range of BRS patented design options helps address evolving metal roof codes and project requirements. These include panel side joinery, fixed and movable standard clips, wind clips, extended stand-off clips, and accessories such as the High Capacity Rake Plate with up to 7 inches of travel.
Three unique field-seaming options, RollLok®, TripleLok®, and QuadLok®, deliver superior performance and design flexibility.

The BRS TS-324 Roof System Designed For The 21st Century Consisting Of:
One Panel profile with three seams.
1. RolLok® - Seam not requiring an electric seamer competing with existing snap together panels
2. TripleLok® - Seam with higher wind and water performance than double lock panels on the market
3. QuadLok® - Seam providing high velocity wind performance without the use of S5 or any other external clamps
Four patented clip options each with increasing uplift ratings.
Eliminates the need to reduce spans or provide external clamps
- 4” Standard
- 8” wind clip
- 12” wind clip
- 16” 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)
TS-324 Roof System is designed around one panel profile that will out-perform existing snap together panels and field seam panels without the addition of external seam clamps.

Consider The Benefits Of Offering All Three Seams:
By licensing the TS-324 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 that BRS Licensees have achieved 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.
• Longer panel runs without fixing at center of span or using step in slope details.
• Ability to compete with the snap-together SSR roof projects with same profile .
Key patented features of the TS-324 system that provide benefits to you and your Customers
- Improved Panel Seam
- Multiple Panel Clips
- Proven Accessories
- Zonal Seaming
ONE PANEL - THREE SEAMS
The TS-324 panel is one panel profile that can be installed using one or more of three seams.
Seam 1 - RollLok™
The RollLok seam is crimped at the panel clips only. The weather tightness and wind uplift ratings are superior to existing snap together panels.
Seam Crimping is accomplished with an inexpensive stand up hand crimper. This process can be accomplished with less time than snapping seams on a snap-together panel.
Seam 2 - 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 3 - 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.
