Premium Steel Deck: Composite, Roof & Form Decking
Tarco delivers high-performance steel deck systems engineered to meet the toughest demands of commercial, industrial, and infrastructure projects. Our entire product line is manufactured from prime galvanized steel, certified to Steel Deck Institute (SDI) standards, and backed by comprehensive load tables and span charts. Whether you need a composite floor deck for a high-rise or a durable roof deck for a warehouse, we provide cost-effective solutions with rapid lead times.
Our Steel Deck Product Lineup
We offer a complete range of cold-formed steel deck profiles to suit diverse span requirements, structural loads, and project budgets. All profiles are available in standard 36” or 32” coverage widths and G60/G90 galvanized coatings.
Composite Floor Deck
Acts as permanent formwork and positive reinforcement for concrete slabs. Deep embossments create a mechanical bond, eliminating temporary shoring and accelerating construction.
- Profiles: 2W (2” x 6”), 3W (3” x 6”), 2” Deep Composite Deck
- Key Uses: Multi-story buildings, parking structures, high-rise towers
- SEO Keywords: composite steel deck, floor decking, shear connectors, slab form deck
Steel Roof Deck
Engineered for superior spanning capability and diaphragm strength. Our B-Deck (1.5” depth) offers lightweight efficiency for shorter spans, while N-Deck (3” depth) maximizes load capacity for longer spans, reducing structural steel costs.
- B-Deck: 36” width, ideal for commercial roofing, 20–26 ga.
- N-Deck: 32” width, nestable option, 20–22 ga, high live loads
- SEO Keywords: roof deck, B deck, N deck, wide rib deck, galvanized roof deck
Cellular & Exposed Ceiling Deck
Combine structure with aesthetics. Our cellular (pan) deck features a flat bottom surface ideal for exposed environments. Acoustic versions with perforations provide noise control for auditoriums, airports, and stadiums.
- Smooth Series™: Blemish-free attachment, reduces field touch-up
- Acustadek: Perforated patterns + sound-absorbing infills
- SEO Keywords: cellular deck, acoustic deck, exposed ceiling deck, Acustadek
Form Deck (Non-Composite)
Permanent formwork for concrete slabs where composite action is not required. Lightweight, fast installation, and provides a safe working platform during concrete placement.
- Typical Depth: 1.5” – 3” corrugations
- Best For: Podium slabs, renovation projects, industrial floors
- SEO Keywords: form deck, non-composite deck, permanent formwork
Technical Data & SDI Compliance
All steel decking products meet or exceed the Steel Deck Institute (SDI) requirements. We provide certified load tables, span charts, and diaphragm shear values to assist structural engineers and contractors in optimizing their designs.
| Deck Type | Depth (in.) | Gauge Range | Typical Span (ft) | SDI Standard |
|---|---|---|---|---|
| Composite Floor Deck (2W) | 2 | 16–20 ga | 5 – 10 | SDI C-2017 |
| Composite Floor Deck (3W) | 3 | 16–18 ga | 8 – 14 | SDI C-2017 |
| Roof Deck – B-Deck | 1.5 | 20–26 ga | 4 – 8 | SDI RD-2020 |
| Roof Deck – N-Deck | 3 | 20–22 ga | 6 – 12 | SDI RD-2020 |
| Form Deck | 1.5 – 3 | 20–26 ga | 3 – 6 | SDI FD-2018 |

Frequently Asked Questions (Steel Deck)
What is the difference between B-Deck and N-Deck?
B-Deck (1.5” depth) is ideal for short to medium spans and is commonly used in roof systems where insulation and membrane are applied. N-Deck (3” depth) provides greater structural capacity for longer spans and is often specified for areas with higher live loads or wider column spacing.
Can you provide composite floor deck with shear studs?
Yes, we offer fully integrated solutions including welded shear stud connectors to achieve composite action. Our deck embossments are engineered to meet SDI composite design requirements for maximum load transfer.
Do you supply load tables for fire-rated assemblies?
Absolutely. Our steel deck load tables include fire-resistance ratings for various concrete thicknesses. Contact our technical department for UL/ULC listed assemblies.
What is the typical lead time for a custom steel deck order?
Standard profiles ship within 1–2 weeks. Custom lengths and special coatings may require 2–3 weeks depending on quantity. Expedited services are available upon request.
