Reveal Wall Panel Dimensions, Joint Spacing, Gauge Range, and Installation Span Tables
Reveal Wall Panel Dimensions, Joint Spacing and Span Tables
The Reveal Wall Panel is an architectural metal wall cladding system designed to create a modern facade with clean vertical or horizontal lines. The system uses flat panels with a recessed joint, commonly referred to as a “reveal,” between adjacent panels.
Reveal wall panels are widely used in commercial, institutional, and architectural buildings because they provide a modern appearance while maintaining durability and weather protection.
Reveal wall panels are commonly used in:
• commercial buildings
• architectural facades
• office buildings
• educational facilities
• retail developments
• hospitals and public buildings
• modern residential projects
These panels are manufactured using precision roll forming machines that shape steel or aluminum coil into flat panels with folded edges and concealed fastening systems.
This guide provides a detailed technical overview of reveal wall panel dimensions, joint spacing, steel gauges, coil width requirements, and span capabilities used by architects, engineers, and metal panel manufacturers.
What is a Reveal Wall Panel
A reveal wall panel is an architectural cladding panel designed with a recessed joint between panels to create shadow lines across the building facade.
Unlike flush wall panels that create a completely smooth surface, reveal wall panels intentionally incorporate a visible joint that enhances architectural design.
Key advantages include:
• modern architectural appearance
• recessed reveal joint design
• concealed fastening system
• weather-resistant wall system
• flexible panel layouts
Because of these characteristics, reveal wall panels are commonly used in modern building facades.
Standard Reveal Wall Panel Dimensions
Reveal wall panels are manufactured in various widths depending on architectural design and project specifications.
Typical dimensions include:
Specification
Typical Measurement
Coverage Width
300 – 600 mm
Overall Width
320 – 650 mm
Panel Depth
20 – 40 mm
Reveal Joint Width
10 – 25 mm
Panel Length
Custom roll formed
Coverage width refers to the visible installed panel width excluding the reveal joint.
Panel Layout and Reveal Joint Design
Reveal wall panels use recessed joints between panels to create architectural shadow lines.
Typical panel layout characteristics include:
• flat panel face
• recessed reveal joint
• folded reinforcing edges
• concealed fastening system
Typical reveal joint dimensions include:
Feature
Measurement
Reveal width
10 – 25 mm
Panel depth
20 – 40 mm
Edge fold depth
12 – 20 mm
The reveal joint creates a visible architectural line between panels.
Reveal Wall Panel Cross Section Dimensions
The cross section of a reveal wall panel consists of a flat face with folded edges designed to interlock with adjacent panels.
Typical cross section characteristics include:
Panel depth
20 – 40 mm
Coverage width
300 – 600 mm
Joint type
Recessed reveal joint
Fixing system
Concealed fasteners
The concealed fastening system ensures that no screws are visible on the exterior surface.
Steel Gauge Range for Reveal Wall Panels
Reveal wall panels are typically manufactured using medium steel gauges to maintain panel flatness and structural stability.
Typical gauges include:
Gauge
Thickness
Typical Application
26 gauge
0.0179 in
Light architectural cladding
24 gauge
0.0239 in
Commercial facades
22 gauge
0.0299 in
High-end architectural buildings
20 gauge
0.0359 in
Structural wall cladding
Thicker gauges help reduce panel oil-canning and improve structural rigidity.
Reveal Wall Panel Span Tables
Reveal wall panels are designed primarily for vertical wall installation rather than roofing applications.
Span capability depends on:
• panel thickness
• panel width
• wind loads
• building height
• structural framing
Typical span ranges include:
Gauge
Wall Span
26 gauge
3 – 4 ft
24 gauge
4 – 6 ft
22 gauge
6 – 8 ft
Engineering calculations must always be performed for specific building designs.
Coil Width Requirements for Reveal Wall Panels
Steel coil must be slit to the correct width before entering the roll forming machine.
Typical coil widths include:
Panel Coverage
Coil Width
300 mm panel
340 – 360 mm coil
400 mm panel
440 – 460 mm coil
600 mm panel
640 – 660 mm coil
Additional material is required to form the panel edges and reveal joints.
Materials Used for Reveal Wall Panels
Reveal wall panels can be manufactured using several metal materials depending on project requirements.
Common materials include:
Galvanized steel
Galvalume steel
Aluminum
Stainless steel
Pre-painted steel
Pre-painted steel and aluminum are commonly used for architectural cladding.
Industries Using Reveal Wall Panels
Reveal wall panels are widely used across architectural and commercial construction sectors.
Typical applications include:
Commercial office buildings
Retail developments
Architectural facades
Educational institutions
Healthcare facilities
Industrial building exteriors
Modern residential architecture
The reveal joint creates distinctive facade lines used in modern architectural design.
Roll Forming Machines Used to Produce Reveal Wall Panels
Reveal wall panels are produced using roll forming machines designed for architectural cladding profiles.
Typical machine specifications include:
Number of forming stations
16 – 24 stations
Roller material
Hardened tool steel
Machine speed
10 – 25 meters per minute
Drive system
Gearbox drive
Cutting system
Hydraulic shear or flying shear
Control system
PLC automatic length control
These machines allow precise production of architectural metal wall panels.
Installation Considerations
Proper installation ensures long-term facade performance.
Important installation factors include:
Correct panel alignment
Reveal joint spacing
Concealed clip installation
Weather sealing at panel joints
Reveal wall panels are typically installed over steel or aluminum sub-framing systems.
Engineering Load Considerations
Architects and engineers designing reveal wall systems must consider:
Wind loads
Thermal expansion
Building height
Subframe design
Panel deflection limits
These panels are commonly installed on structural girts or wall framing systems.
Common Manufacturing Problems
Manufacturing issues may occur if roll forming machines are not properly adjusted.
Common issues include:
Panel oil-canning
Joint misalignment
Edge distortion
Panel waviness
Proper tooling alignment and correct material thickness help prevent these issues.
