Column Formwork: Types, Sizes and Assembly

A practical guide for site managers and clients: which formwork suits square, rectangular or round columns, how it goes together, how many sets you need, and whether renting or buying makes more sense.

Types of Column Formwork: Which to Choose

The column shape decides the system. Most framed buildings only need panel formwork; architectural and car-park columns usually call for round forms.

Panel formwork for square and rectangular columns

Four panels stand around the rebar cage and are joined with corner pieces and clamps. The section is set by where the panels sit, so one set can be re-adjusted for a different column.

  • •Sections from 200×200 to 800×800 mm
  • •Adjustable panels 0.3–1.2 m wide
  • •Corner pieces, clamps and ties included
  • •Straight faces with no follow-up levelling

Choose it for: concrete-frame housing, warehouses and car parks — any job where the same column section repeats floor after floor.

Round column formwork

Two half-shells in steel or plastic are clamped together along vertical flanges. The inner face is smooth, so the column comes out seamless and needs almost no finishing.

  • •Diameters from 200 to 800 mm
  • •Steel or plastic shells
  • •Columns up to 400 mm are set by hand by 2–3 workers
  • •Height is built up in sections

Choose it for: lobbies, retail halls, car parks and facade columns where appearance matters. Single-use cardboard tubes can do for a handful of columns, but reusable shells pay off on a series.

Formwork for non-standard sections

Elliptical, polygonal or T-shaped columns cannot be formed with standard panels. We make this formwork to your drawing.

  • •Elliptical, polygonal and T-shaped columns
  • •Made in 7–14 days
  • •Minimum order: 4 sets
  • •Priced from the column drawing

Choose it for: architectural projects with a distinctive column shape repeated across the building.

Geometric accuracy is within 2 mm per metre of height, so the columns do not need plastering to straighten the faces.

Need a size that is not in the table? We make formwork to order for non-standard sections.

How Column Formwork Is Assembled

Six steps from rebar cage to finished column

  1. 1

    Prepare the base

    Mark the column axes on the slab or footing and clean the base. The rebar cage must stand plumb, with cover spacers fitted.

  2. 2

    Oil the panels

    Coat the panel faces with formwork release agent. Concrete will not stick, stripping is easier and the column surface stays clean.

  3. 3

    Assemble around the cage

    A rectangular column is enclosed by four panels locked with corner pieces and clamps. A round one is formed by two half-shells joined at the flanges.

  4. 4

    Plumb and brace

    Set the formwork vertical with a level or plumb line, check the diagonals and fix push-pull props on two sides so the column cannot drift during the pour.

  5. 5

    Pour

    Place concrete in layers and compact it with a poker vibrator. On tall columns the sections are added as you go so concrete is not dropped from a height.

  6. 6

    Strip

    At around +20 °C keep the formwork on for at least 5–7 days while the concrete gains strength. Then remove, clean and oil the panels for the next column.

How to Calculate Column Formwork

Two numbers you need to order: formwork area per column and the number of sets

Area per column

For a rectangular column the formwork area is the section perimeter times the height. For a round one it is the circumference (3.14 × diameter) times the height.

  • 400×400 mm column, 3 m high: (0.4 × 4) × 3 = 4.8 m²
  • Round Ø400 mm column, 3 m high: 3.14 × 0.4 × 3 ≈ 3.8 m²

How many sets you need

You need as many sets as columns you pour at the same time, not as many as there are on the floor. After stripping, the same set moves on to the next column.

Example: a floor has 40 identical columns and the crew pours 8 at a time. You need 8 sets, each doing 5 cycles. The tighter the schedule, the more sets.

  • •Number of columns and their sections or diameters
  • •Column height, floor to floor
  • •How many columns you pour at once
  • •Programme dates, to compare renting with buying

How Much Column Formwork Costs

Rent it, buy it new or used, or sell yours to us

ServicePrice
Column formwork rentalfrom ₴4,000 per set (one column) a month, minimum term 15 days
New column formworkprice on request
Used column formworkask for price and availability
Formwork buybackpriced after inspection, depending on condition, volume and current demand

Prices are indicative. The final cost depends on the column section, height, number of columns and hire period. Delivery in Kyiv starts from ₴700, elsewhere in Ukraine it is quoted per order; collection from our yard costs nothing.

Renting pays when columns are on one site only: you pay for the working period and return the formwork. Buying makes sense when columns come in series across several sites in a row — and once the build is done, you can sell the formwork back to us.
