What Is a Linear Curved Grille? Specs and How to Specify One
A linear curved grille follows a curved wall or ceiling line instead of running straight, keeping the linear look on non-flat surfaces. Specs, applications, and how to specify one.
A linear curved grille is an HVAC air terminal built to follow a curved wall or ceiling line, keeping a continuous linear look on surfaces where a straight grille wouldn't fit cleanly. Goodwind manufactures the Linear Curved Grille (model GT-LCG) in aluminum, steel, or custom material, for commercial, residential, and industrial projects.

Where Linear Curved Grilles Are Used
Curved architectural features — rounded ceiling coves, bowed walls, circular atriums — don't take a straight linear grille cleanly; the run either has to break into short straight segments or get replaced with a different product entirely. A linear curved grille solves that by following the actual curve, so the linear look continues uninterrupted across a radius rather than faceting around it.
How to Specify a Linear Curved Grille
For MEP Consultants at the Design Stage
Specify a linear curved grille wherever the linear run needs to follow an architectural radius rather than a straight line, and provide the actual radius dimension from the drawings, since these are built to the specific curve rather than a stock bend. Where the wall or ceiling is flat, a standard slot or linear bar grille remains the simpler choice.
For Contractors at Procurement Stage
Confirm the exact radius and mounting method against the drawing before ordering, since this product is manufactured to the specified curve rather than stocked in standard dimensions. Field-verify the radius on site where possible, since architectural curves don't always match the drawn dimension exactly.
FAQ
What is a linear curved grille used for?
It's used where a linear grille run needs to follow a curved wall or ceiling instead of a straight line, keeping a continuous look across the radius.
How is the radius determined for a linear curved grille?
From the project drawings, ideally confirmed with a field measurement of the actual curve before the grille is manufactured.
Can linear curved grilles be custom sized and finished?
Yes. They're manufactured in a range of sizes and finishes, including powder coating and anodizing, to match project requirements.
What materials are linear curved grilles made from?
Aluminum, steel, or custom material.
