C.H.I. Planks Collection

Overview

Horizontal plank siding is common in modern farmhouse, barn-style, and contemporary residential design. The C.H.I. Planks Collection brings that same look to a steel garage door. It does this by pressing recessed horizontal accent lines into a textured steel panel.

From the street, the door reads as a series of horizontal planks. It matches the look of horizontal board and batten, shiplap, or plank siding. It does not add a different surface to the facade. Because the pattern is stamped into the steel, there are no separate inserts, overlays, or channels. This means less debris buildup and no water sitting in seams. The surface is clean and easy to maintain.

This is a steel sectional door at its core. It runs on standard hardware and works with standard openers. It is available in the same insulation tiers as other C.H.I. steel collections. The only difference is the panel surface treatment. That makes the Planks Collection easy to specify for any project that needs a horizontal-plank look in steel. It is a practical, low-maintenance way to match a horizontal siding theme on the garage door.

Construction and materials

The Planks Collection is built on steel panels in three gauge options. Gauge refers to the thickness of the steel. A lower gauge number means thicker steel.

• 25 ga: A cost-effective starting point. Good for homeowners who want the plank look at a lower price.
• 24 ga: A heavier-gauge option. It adds dent resistance. Recommended for active households or areas prone to hail.
• 27 ga: Available for specific configurations. Confirm the available combinations with your dealer.

Construction layers:

• 1-Sided Steel: Steel exterior with an open interior.
• 1-Sided Steel with Vinyl Back: Adds a vinyl interior facing for a finished look inside the garage.
• 2-Sided Steel: Steel on both faces. The stiffest option with the cleanest interior appearance.

All configurations are 2 inches thick.

Insulation options and R-values:

• Uninsulated
• Polystyrene: R-7.94 or R-10.29
• Polyurethane: R-17.54

R-value measures how well a material resists heat flow. A higher R-value means better insulation. The polystyrene options use rigid foam boards placed between the steel skins. The polyurethane option uses foam injected between the skins. Polyurethane bonds to both surfaces. It fills the cavity more completely and provides both better thermal insulation and added panel stiffness. At R-17.54, the polyurethane option matches the top insulation tier offered on C.H.I.'s other high-performance lines.

Sections carry a limited lifetime warranty. Springs carry a 3-year warranty and hardware a 6-year warranty.

Styles, colors, and window options

The surface texture of the Planks Collection comes from the stamped horizontal accent lines and the textured steel. Color and window choice can change the look significantly.

Standard paint colors:

White, Almond, Sandstone, Brown, Bronze, Gray, Desert Tan, Black, Graphite

Wood-look finishes:

• Painted Woodtones: Factory-applied wood-inspired paint finishes that complement the plank visual.
• Accents Woodtones: Textured wood-grain surface treatment on steel for a more pronounced wood-look appearance.

Powder coat: 188 colors available. This allows color matching to almost any exterior paint or trim scheme. With 188 powder coat options, finding a close match to an existing exterior color is rarely a problem.

Window options:

Short, Long, Oversized, StyleLite inserts in the following glass types:

Plain, Obscure, Tinted, Rain Glass, Frosted, Seeded, Designer Glass

Long horizontal window inserts pair especially well with the horizontal plank texture. They continue the horizontal theme of the panel surface. A door in a dark color like Graphite, Bronze, or Black with a long Frosted glass insert is a common choice for barn-style and modern farmhouse applications. The horizontal lines of the glass insert echo the horizontal lines of the plank pattern. The result is a door with a strong, unified visual character.

Short window inserts work too. They create a different rhythm on the door face. Some homeowners prefer a shorter insert because it lets in light without making the door feel too open. The StyleLite insert is a narrow horizontal option that adds a subtle light band without dominating the surface.

Is it right for your Colorado home, and how G Brothers helps

Horizontal plank siding and barn-style details are now common in new Colorado residential construction. From Broomfield to Castle Rock and from Aurora to the foothill communities west of Denver, modern farmhouse and barn-style builds are popular. The garage door is one of the most visible parts of that design. The Planks Collection gives you a steel door that fits right into those projects without looking like a compromise.

Steel has real advantages over wood in Colorado. At Front Range elevations, ultraviolet intensity is high. Humidity is low. Temperature swings between seasons are big. Real horizontal wood planking on a garage door needs regular refinishing. It can also split and warp over time. A steel door with a stamped plank pattern and a Woodtones finish holds up to Colorado's climate with far less maintenance. The factory-applied finish on a steel door is more durable than any field-applied paint or stain.

For attached garages, the R-17.54 polyurethane insulation option is a smart upgrade on the Front Range. Colorado winters can drop into the single digits or below zero across the metro. An insulated door makes a real difference in how comfortable nearby rooms stay. It also helps with energy costs. A door with good insulation reduces how hard the furnace has to work to keep the home warm on cold mornings.

The 24 ga steel option adds dent resistance. That matters in a hail-prone region. The Front Range sees significant hail activity in late spring and early summer. A heavier-gauge door is more likely to come through a hail event without visible damage. The cost difference between 25 ga and 24 ga is modest. For many homeowners, the added protection is worth it.

Think about your typical use of the garage too. If you park cars, ride bikes, or use the garage as a work area, the door gets a lot of use. A 24 ga door stands up to daily impact better than 25 ga. If the garage is mostly storage, 25 ga may be all you need.
