Our people are a diverse group; backgrounds include engineers, educators, garden center managers, and growers, all working together to help you reach your dreams. From thermostats to computer-driven environmental controls or hand-watering to Ebb and Flo Benches, we can help you determine your needs.
| FEATURES |
With a 6/12-roof slope, the raised peak of the A-Frame provides increased air volume, therefore less fluctuation in air temperature, providing the ideal environment for you, your plants, your customers, your employees, and your students. Standard and custom widths and various heights are available to accommodate your needs.
Designed to readily accept hanging baskets, booms, echo systems, and other needed equipment, the Rough Brothers' A-Frame truss system can be designed to support each piece of supplementary equipment. This truss has also been designed for use with heat retention and shading systems, minimizing summer heat gain and winter heat loss.
Rough Brothers is proud of our reputation for superior quality. Standard sizes include 20'6", 24', 30', 36', 42' and 50'; complete design specifications and structural details are available.

Available Widths
The standard widths of the A-Frame structures are 20'-6", 24'-0", 30'-0", 36'-0", 42'-0" and 50'-0" wide. Custom widths are always available. The structural details below are based on a 30'-0" width.
Gutter Posts
Posts are to be set directly into the concrete pier or on post stubs in the concrete pier. The pier size will be determined by loading requirements determined by engineering.
Post Top
A cast post top with an integral drip gutter support will bolt to the post and support the gutter saddle.
Gutter Saddle
A galvanized steel gutter saddle will be at each post to splice the gutter and to bolt to the post top. The gutter saddle has 8 holes to bolt to the gutter. The seal between the gutter saddle and the gutter is created using a black "puttylastic" strip.
Downspouts
Cast aluminum downspout is used where downspouts are required. The hole in the gutter is predrilled for ease of installation of the downspout.
Gutter Extensions
There are many options in the gutter extensions depending on the situation:
- Open ended to let the water run off the greenhouse
- Welded end with no downspout
- Welded in with a downspout
Trusses
At each interior post there will be a truss which shall span across the structure at 12'-0" centers. Trusses to be galvanized steel tubing with welded construction. Each truss to be constructed of (2) halves, slipped together on site. The truss provides simplified installation of additional equipment such as:
