Short answer
Misc metals are priced by unit (per flight of stairs, per linear foot of rail, per each) built up from shop hours, material, finish and installation, not by tonnage. They carry far more labor per pound than structural framing, so a cost-per-ton rate from beam work will underprice them.
Why per-ton pricing fails
A floor beam is one cut, a few holes and two clip angles. A stair stringer weighs less and carries layout for every tread, welds at every step, top and bottom connections and rail posts. The steel is a small part of the cost; the touches are the cost.
Shop hours tell the story. Structural framing commonly runs on the order of 12 to 45 man-hours per ton depending on complexity, while stairs and railings run 60 to 120 or more, and gates, ladders and small fabrications can go well above that. Applying a structural per-ton price to a misc package is the classic way to lose money on it.
The usual units
| Item | How it is typically priced |
|---|---|
| Stairs | Per flight, by rise, width and tread type |
| Pipe handrail and guardrail | Per linear foot, by type and mounting |
| Ladders and cages | Per vertical foot or each |
| Bollards, lintels, shelf angles | Each or per linear foot |
| Embeds and anchor plates | Each |
| Grating, checker plate | Per square foot or per piece |
Each shop has its own numbers, built from its labor rates, finish costs and installation method. Published ranges (see the linked guides) help as a sanity check only.
How do you take off misc metals?
Misc metals hide in the set. Stairs and rails are on architectural sheets as well as structural ones. Lintels and shelf angles appear in wall sections. Embeds and bollards live in details and site sheets. Read the specification section for metal fabrications and every detail callout, not just the framing plans.
Measure rails along the centerline of the slope, not the plan dimension. Count posts, returns and terminations separately. Note finish: galvanizing, powder coat, paint and stainless each add cost and lead time. For a worked stair, see the stair cost guide.
What should a misc metals bid include?
Shop drawings, material, fabrication, finish, delivery, and installation if you are installing. State what is excluded: field welding by others, concrete, core drilling, glazing, painting after erection. Misc metals scope disputes usually come from an unclear line between the structural package and the architectural one, so write the scope letter carefully.
SteelFlo's takeoff handles the framing members that carry designations and gives you a bill of materials you can price; the unit pricing above stays your own judgment.
A worked example: how a stair price builds up
Consider one straight steel stair flight with channel stringers, checker plate treads and pipe handrail on both sides. A shop would typically build the price from:
- Material: stringers, tread pans or plates, landing frame, rail pipe and posts, based on weights and current quotes.
- Shop labor: layout, cutting, welding the treads, assembling, grinding, based on the shop's own hours for a stair of that size.
- Finish: primer, paint, galvanizing or powder coat.
- Shop drawings and engineering if the stair needs them.
- Delivery and installation, including a crane or lift if needed.
- Overhead and margin.
Published ranges in our guides put a flight of steel stairs in the thousands of dollars and pipe rail at roughly $80 to $150 per linear foot installed, but your own costs and your region will differ, so treat those as sanity checks. See Steel stair cost per flight.
Common misc metals pitfalls
- Scope gaps. Nobody priced the loose lintels, or both the steel sub and the architectural metals sub assumed the other had the ladder.
- Finish costs missed. Galvanizing adds kettle trips and vent holes. Powder coat needs oven size and lead time.
- Field conditions. Core drilling, anchor types and existing walls vary from the drawing.
- Submittal time. Ornamental work can mean many review cycles.
- Plan dimension versus true length. Rail follows the stair slope, so plan length understates it.
Write exclusions into the bid so the next person cannot assume them.
Should misc metals be priced separately from structural?
Usually yes. Separate line items let the GC compare apples to apples and let you apply different markups. They also make it easier to drop or add scope. A single blended price per ton for the whole package makes the bid look simple and the profit hard to see.
