PRODUCT DESCRIPTION
AMP · Architectural Metal Trellises
Roundline Trellis
Clean horizontal rhythm. Solid round-bar construction.
The Roundline Trellis combines a strong architectural angle frame with horizontal solid round steel bars to create a simple, versatile framework for climbing vegetation.
Design Character
Solid 1/2″ round bars create softer edges and clean linear shadows while maintaining consistent horizontal spacing at approximately 6″ C/C.
Architectural Applications
- Exterior feature walls
- Climbing vegetation support
- Courtyards and garden walls
- Residential entryways and façades
- Hospitality and landscape architecture
- Custom architectural projects

Steel Construction
Each Roundline Trellis is fabricated as a welded architectural steel assembly. The selected overall width and height are the finished exterior dimensions of the trellis.
Frame: 1-1/2″ × 1-1/2″ × 3/16″ steel angle perimeter frame.
Interior: 1/2″ solid round steel bar.
Geometry: Horizontal members at 6″ C/C; first bar center is positioned 3″ from the interior top edge.
Stand-Off Mounting System
4", 6", and 8" Fixed Stand-Off: standard attachment points use 1" × 3/16" steel flat-bar stand-offs extending from the trellis to the mounting surface. Each standard mounting point includes one attachment hole.
Adjustable 8"–12": a telescopic steel mounting system using 1" × 1" × 1/8" inner tube and 1-1/4" × 1-1/4" × 1/8" outer tube allows depth adjustment for uneven wall conditions.
Wall anchors are not included. Anchor type, size, embedment, and substrate suitability must be selected by the installer or project professional for the actual wall construction and field conditions.
Standard Trellis Sizes
Widths: 24", 30", 36", 42", 48", 60".
Heights: 48", 60", 72", 84", 96", 108", 120".
Widths of 72", 84", 96", 108", and 120" are handled as Custom Project / Request a Quote configurations rather than standard online variations.
Surface Preparation & Finish
Sandblast → Zinc Primer → Powder Coat
The fabricated steel is prepared by sandblasting, followed by zinc primer and the selected architectural powder-coat finish.
Standard Architectural Finishes
- Black — standard textured black powder coat
- White
- Dark Gray
- Bronze
Digital color samples are representative only. Actual finish appearance may vary with lighting, display settings, texture, and production conditions.
Installation & Attachment
Final attachment requirements depend on substrate, wall construction, project location, product size, stand-off depth, environmental exposure, and field conditions. AMP supplies the fabricated trellis and selected stand-off configuration; field anchors are selected and supplied by the installer.
Plant Growth & Maintenance
Plant selection, training, irrigation, pruning, and maintenance remain project-specific. Allow appropriate clearance between vegetation and the building envelope and inspect attachment points periodically.
Custom Architectural Projects
AMP can review custom widths, project quantities, alternate mounting conditions, and project-specific trellis requirements. Standard online widths stop at 60"; larger widths are quoted separately.
Product Use Notice
This product is intended as an architectural trellis and plant-support feature. It is not automatically designed or represented as a guardrail, fall-protection system, security barrier, pool barrier, structural fence, or other life-safety system.
