Deck Profile Explorer
Steel deck comes in various profiles, each engineered for a specific function. Click on a card to learn more about its characteristics and common applications.
B-Deck (Wide Rib)
The most common and structurally efficient roof deck, ideal for new commercial roofs.
N-Deck (Deep Rib)
Engineered for long spans (up to 16 ft+), reducing the need for intermediate supports.
1.5" Composite
Features embossments to bond with concrete, acting as tensile reinforcement.
3.0" Composite
Deepest standard profile, allowing for the longest unpropped spans during construction.
1.5C Form Deck
Acts as a permanent, stay-in-place form for concrete slabs where composite action is not needed.
Cellular Deck
A flat steel sheet welded to a standard profile, creating enclosed cells for utilities.
The Estimation Workflow
A successful estimate follows a systematic process. This workflow outlines the critical path from initial analysis to the final bid.
Analyze Drawings
Identify deck types, gauges, finishes, and fastening patterns from structural plans.
Material Takeoff
Calculate net area, apply waste factors, and quantify all accessories and fasteners.
Cost Buildup
Apply unit costs for materials, labor, and equipment. Add overheads and profit.
Final Bid
Compile all costs into a comprehensive, competitive, and profitable bid package.

Fastening Systems: A Head-to-Head Comparison
The choice between welding and mechanical fastening significantly impacts labor costs, schedule, and site safety. Here's how they stack up.
🔥 Arc Spot Welding
-
✓
Highest Strength: Produces the strongest and stiffest connections, potentially allowing for a less dense fastening pattern.
-
✗
Slower & Labor-Intensive: Requires a certified, higher-paid welder, increasing man-hours.
-
✗
Safety Hazards: Generates hazardous fumes and fire risks from sparks, requiring a dedicated fire watch and ventilation.
-
✗
Coating Damage: The heat can damage the deck's protective coating, necessitating field touch-ups to prevent corrosion.
🔩 Mechanical Fasteners
-
✓
Speed & Efficiency: Significantly faster to install, directly reducing total man-hours and labor costs.
-
✓
Improved Safety: Eliminates fume and fire hazards, removing the need for a fire watch and specialized ventilation.
-
✓
Lower Skill Requirement: Can be installed by general laborers, reducing the blended hourly crew rate.
-
✗
Material Cost: Individual screws or pins can have a higher unit cost than welding rods, though this is often offset by labor savings.
