Floor deck profiles fail on long spans for one main reason. The rib depth does not match the span the sheet must carry before the concrete cures. A long-span floor deck is any steel deck profile designed to carry wet concrete across 4.5 m or more without temporary shoring.<\/p>

This article gives you 6 rib depth engineering rules for 4.5 m unshored spans. You will see which rib depths work, how gauge pairs with depth, and what the deflection limits allow. We also cover what a deep deck profile demands from a\u00a0floor deck roll forming machine<\/a>.<\/p>

Every rule here reflects how Beli Rollforming engineers deep deck tooling for fabricators across more than 20 countries.<\/p>

Why Rib Depth Governs the Unshored Span<\/h2>

An unshored span is the distance a steel deck sheet must bridge between beams with no temporary props underneath. The deck carries itself, the wet concrete, and construction loads during this stage. This is the most stressed condition in the life of a floor deck profile.<\/p>

Structural capacity in this stage comes almost entirely from section modulus. Deeper ribs place more steel away from the neutral axis, which raises stiffness faster than any other geometry change. A 76 mm rib is roughly 4 times stiffer than a 38 mm rib of the same gauge.<\/p>

Le\u00a0Institut des pontons en acier (SDI)<\/a>\u00a0publishes the span tables most North American engineers use. The pattern in those tables is consistent. Deeper profile, longer unshored span. The table below shows the typical working ranges.<\/p>
Rib Depth<\/th>Type de profil<\/th>Typical Unshored Span<\/th>Common Application<\/th><\/tr>
38 mm (1.5 in)<\/td>Shallow deck<\/td>Up to 2.4 m<\/td>Tight joist spacing, short bays<\/td><\/tr>
51 mm (2 in)<\/td>Standard deck<\/td>2.4 to 3.0 m<\/td>Office floors, mixed bays<\/td><\/tr>

100 to 125 mm (4 to 5 in)<\/td>Long-span deep deck<\/td>4.5 to 6.0 m<\/td>Column-free floors, transfer levels<\/td><\/tr><\/tbody><\/table>

For a 4.5 m unshored span, the 76 mm class is the practical starting point. A\u00a0fa\u00e7onneuse \u00e0 rouleaux pour pont composite<\/a>\u00a0built for this depth class must form the deep ribs without springback distortion at the rib root.<\/p>

\"Why<\/p>

6 Rib Depth Engineering Rules for 4.5 m Spans<\/h2>

Rule 1: Match Rib Depth to Span Before Anything Else<\/h3>

Rib depth selection comes first because it fixes every other decision. A 4.5 m unshored span needs a 76 mm deep deck profile at minimum. Shallower profiles cannot reach that span at any practical gauge.<\/p>

Pushing a 51 mm profile to 4.5 m fails on deflection, not strength. The sheet may hold the concrete weight, but it sags past allowable limits. The ponding effect then adds even more concrete in the low spot, which adds more load. This feedback loop is the classic long-span floor deck failure mode.<\/p>

Deep profiles from 100 to 125 mm reach 4.5 m with margin and stretch to 6.0 m at heavier gauges. Verify against SDI load tables for your exact slab depth before committing tooling money.<\/p>

Rule 2: Pair Gauge With Depth, Never Gauge Alone<\/h3>

Thickness and depth work as a team. A 76 mm profile spanning 4.5 m needs 1.2 to 1.5 mm (16 to 18 gauge) steel. The same profile at 0.8 mm drops to roughly 3.0 m of unshored capability.<\/p>

Steel grade matters as much as thickness. Most deck sheet is\u00a0ASTM A653<\/a>\u00a0Structural Steel Grade 33, 40, or 50. Moving from Grade 33 to Grade 50 can add 10 to 15 percent span at the same gauge because higher yield steel resists the bending stress better.<\/p>
Deck Gauge<\/th>Steel Thickness<\/th>76 mm Profile Span<\/th>Grade 50 Span Gain<\/th><\/tr>
22 gauge<\/td>0.76 mm<\/td>3.0 to 3.6 m<\/td>+0.3 m<\/td><\/tr>
20 gauge<\/td>0.91 mm<\/td>3.6 to 4.2 m<\/td>+0.4 m<\/td><\/tr>
18 gauge<\/td>1,2 mm<\/td>4.2 to 4.5 m<\/td>+0.5 m<\/td><\/tr>
16 gauge<\/td>1,5 mm<\/td>4.5 to 5.0 m<\/td>+0.6 m<\/td><\/tr><\/tbody><\/table>

Design the profile for the thinnest gauge you will sell, then confirm the heavy gauge still forms cleanly in the same tooling.<\/p>

Rule 3: Hold Deflection to L\/180 or 20 mm During the Pour<\/h3>

Deflection, not strength, sets the real span limit. The common SDI-based limit for deck under wet concrete is the span divided by 180, or an absolute cap of 20 mm (3\/4 inch), whichever is smaller. At 4.5 m, the L\/180 value is 25 mm, so the 20 mm absolute cap governs.<\/p>

Excess deflection creates concrete ponding. Concrete flows to the low point, the slab thickens there, and the load grows beyond the design value. Field fixes are expensive. Pouring a leveling topping over a sagged deck can add 15 to 20 mm of extra concrete across the bay.<\/p>

Check the deflection case with the full slab depth plus a construction live load of 1.0 to 1.5 kPa. The\u00a0Institut am\u00e9ricain de la construction en acier (AISC)<\/a>\u00a0publishes design guides that walk through this load combination for composite floors.<\/p>

Rule 4: Design Rib Geometry for Stiffness, Not Just Depth<\/h3>

Depth alone is not enough. Rib width controls how efficiently that depth works. Narrow ribs at 40 to 50 mm top width concentrate the steel webs and raise the moment of inertia per meter of cover width. Wide ribs at 150 mm or more dilute stiffness even at 76 mm depth.<\/p>

Keep the rib walls flared between 10 and 20 degrees from vertical. This flare lets the profile roll form without web wrinkling and keeps the concrete keys locked into the rib valleys. Vertical rib walls roll harder and risk oil canning on the bottom flange.<\/p>

Bottom flange width also matters for bearing. SDI detail practice calls for at least 50 mm of end bearing on supports. Thin metal bearing on a narrow flange at 4.5 m span invites local web crippling, which is a sudden failure mode.<\/p>

Rule 5: Verify Embossments for the Composite Stage<\/h3>

The unshored span is a construction stage problem. After the concrete cures, the floor deck profiles act compositely with the slab. The embossments rolled into the rib webs create that bond. Embossment pattern, pitch, and depth are specified in the deck manufacturer’s evaluation report.<\/p>

A typical composite embossment is 2 to 3 mm deep, pitched at 50 to 80 mm along the rib web. That pattern delivers the horizontal shear transfer most published composite deck tables assume. Weak or inconsistent embossments drop the composite section modulus, sometimes by 20 percent or more.<\/p>

For machine buyers, this is a tooling precision question. Embossment rolls wear. Ask for hardened D2 or DC53 steel embossment rollers with a documented 200,000 linear meter service interval. Our\u00a0floor deck profile quality guide<\/a>\u00a0covers the full tooling checklist.<\/p>

Rule 6: Size the Roll Forming Machine to the Profile Depth<\/h3>

Deep deck profiles need more forming stands than shallow ones. A 38 mm profile forms cleanly in 14 to 18 stands. A 76 mm deep deck profile needs 24 to 30 stands so each pass bends the ribs gradually. Forcing deep ribs through few stands produces twist, edge wave, and springback at the rib root.<\/p>

Shaft diameter and roller blank size scale up too. Long-span deep deck tooling runs on 80 to 100 mm shafts, versus 60 to 75 mm for shallow profiles. Under-sized shafts deflect under the higher forming force of deep ribs, and the profile tolerances drift.<\/p>

These machine requirements are why a purpose-built\u00a0machine \u00e0 platelage en acier<\/a>\u00a0for deep profiles costs more than a shallow deck line, and why the investment pays back on long-span projects. Tooling resources from\u00a0Le fabricant<\/a>\u00a0describe the same stand count logic for any deep section.<\/p>

\n\t\t\t\t\t
<\/path><\/svg><\/span><\/path><\/svg><\/span>What rib depth do I need for a 4.5 m unshored span?<\/span><\/path><\/svg><\/div>

A 4.5 m unshored span requires a 76 mm (3 inch) deep deck profile at 1.2 mm (18 gauge) or thicker steel. For extra margin, 100 to 125 mm profiles reach the same span at lighter gauges and stretch to 6.0 m at heavier ones.<\/p><\/div>\n\t\t\t\t\t<\/div>

\n\t\t\t\t\t
<\/path><\/svg><\/span><\/path><\/svg><\/span>What is an unshored span in floor deck construction?<\/span><\/path><\/svg><\/div>

An unshored span is the distance a steel deck sheet bridges between structural supports with no temporary props, while carrying wet concrete and construction loads. The long-span floor deck profile must resist this load case alone before the slab gains strength.<\/p><\/div>\n\t\t\t\t\t<\/div>

\n\t\t\t\t\t
<\/path><\/svg><\/span><\/path><\/svg><\/span>What is the maximum unshored span for a 1.5 inch floor deck?<\/span><\/path><\/svg><\/div>

A 38 mm (1.5 inch) floor deck profile typically spans no more than 2.4 m without shoring. Beyond that distance, deflection under wet concrete exceeds the allowable 20 mm limit, even at heavy gauge.<\/p><\/div>\n\t\t\t\t\t<\/div>

\n\t\t\t\t\t
<\/path><\/svg><\/span><\/path><\/svg><\/span>What deflection limit applies to floor deck during the concrete pour?<\/span><\/path><\/svg><\/div>

The standard deflection limit is span divided by 180 or 20 mm absolute, whichever is smaller, measured under wet concrete plus construction live load. At a 4.5 m unshored span, the 20 mm cap governs because L\/180 equals 25 mm.<\/p><\/div>\n\t\t\t\t\t<\/div>

\n\t\t\t\t\t
<\/path><\/svg><\/span><\/path><\/svg><\/span>Does rib depth change the roll forming machine requirements?<\/span><\/path><\/svg><\/div>

Yes, a 76 mm deep deck profile needs 24 to 30 forming stands and 80 to 100 mm diameter shafts, compared with 14 to 18 stands and 60 to 75 mm shafts for a 38 mm profile. Under-specifying the machine causes twist, edge wave, and rib root springback.<\/p><\/div>\n\t\t\t\t\t<\/div>

\n\t\t\t\t\t
<\/path><\/svg><\/span><\/path><\/svg><\/span>What steel grade is best for long-span floor deck profiles?<\/span><\/path><\/svg><\/div>

ASTM A653 Structural Steel Grade 50 delivers 10 to 15 percent more unshored span than Grade 33 at the same gauge. Grade 40 is a common middle option that balances cost and span for 76 mm deep deck profiles.<\/p><\/div>\n\t\t\t\t\t<\/div>

\n\t\t\t\t\t
<\/path><\/svg><\/span><\/path><\/svg><\/span>How does rib depth affect concrete volume per square meter?<\/span><\/path><\/svg><\/div>

Deeper floor deck profiles require more concrete to reach a level finish, roughly 0.02 to 0.03 cubic meters per square meter for each 25 mm of added rib depth. Structural engineers weigh this added dead load against the shoring cost saved.<\/p><\/div>\n\t\t\t\t\t<\/div>

\n\t\t\t\t\t
<\/path><\/svg><\/span><\/path><\/svg><\/span>Can one floor deck machine form both shallow and deep profiles?<\/span><\/path><\/svg><\/div>

Yes, when the machine is built with enough stands and shaft stiffness for the deepest profile planned, typically 26 to 30 stands for a mixed deep and shallow line. Quick change cassette tooling keeps profile swap time under 3 hours on a well equipped floor deck roll forming machine.<\/p><\/div>\n\t\t\t\t\t<\/div>

\n\t\t\t\t\t
<\/path><\/svg><\/span><\/path><\/svg><\/span>What tolerance does the SDI allow on rib height?<\/span><\/path><\/svg><\/div>

The Steel Deck Institute allows rib height to vary within approximately 2.4 mm (3\/32 inch) of nominal on roll formed deck. Rib height control is critical for long-span profiles because every millimeter of depth loss reduces section modulus.<\/p><\/div>\n\t\t\t\t\t<\/div>

\n\t\t\t\t\t
<\/path><\/svg><\/span><\/path><\/svg><\/span>Do deep deck profiles cost more to roll form than shallow ones?<\/span><\/path><\/svg><\/div>

Yes, deep deck tooling costs 30 to 50 percent more than shallow deck tooling because it uses more stands, larger roller blanks, and heavier shafts. The premium is justified wherever 4.5 m unshored spans eliminate shoring labor on site.<\/p><\/div>\n\t\t\t\t\t<\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t

Conclusion<\/h2>

Rib depth is the master variable in long-span floor deck design. Match the profile depth to the span first, then pair gauge and grade, then check deflection against the 20 mm cap. Design the rib geometry for stiffness, verify the embossments for composite action, and size the roll forming machine with enough stands for deep ribs.<\/p>
