Shoring Posts
HERMEQ supplies shoring posts and the fittings that go with them for temporary structural support in new construction and remodeling. The adjustable steel posts come in a run of sizes and carry ceilings, beams and walls while the permanent structure is removed, built or cured. Push-pull braces give angled support to formwork, walls and precast panels under controlled loads. Fixed and adjustable U-heads fit the posts and system scaffolding to hold timber or steel beams in place, and the PropMate lintel support carries the brickwork above a new opening in a masonry wall.
Steel shoring posts, braces, U-heads and lintel supports
The range divides into vertical posts that carry load from above, push-pull braces that hold walls and panels at an angle, and the heads and supports that fit a post to the load it picks up.
Adjustable steel shoring posts
These are the load-carrying posts of the range: telescopic steel columns that hold up ceilings, beams, slabs and lintels. The adjustable steel shoring posts run in sizes 0 to 4, which together cover clear heights from 3.4 ft to 16 ft, and a screw thread sets the final height without tools. Choose them for any job where the weight comes down from above.
Push-pull braces
A push-pull brace is a raking strut fixed between a wall or panel and the floor slab, where it pushes or pulls the element into plumb and holds it there. The push-pull braces are made for wall formwork, wall alignment and tilt-up or precast panels. Choose them when the job is holding something upright and in line.
U-heads for shoring posts
A U-head sits in the top of a shoring post or a system scaffold standard and cradles a timber or steel beam in its slot, so the beam cannot slide sideways off the post. HERMEQ supplies fixed and adjustable U-heads in several widths to take common beam sizes. Choose a U-head whenever posts carry beams or formwork bearers.
PropMate lintel support
The PropMate lintel support is a steel masonry support that slides into a mortar joint in a double-wythe brick wall and rests on the head of an adjustable shoring post. Choose it for new openings and lintel replacement in load-bearing masonry.
Vertical shoring posts or push-pull braces
The direction of the load decides it. A vertical shoring post takes weight from above and passes it down to the floor or ground, so it is the product for ceilings, beams, slabs, lintels and any formwork that has to carry wet concrete. A push-pull brace works at an angle and resists sideways movement, holding a wall, a precast or tilt-up panel, or a run of wall forms plumb while it is fixed, cast or cured.
The push-pull braces are made for controlled loads and are not a replacement for full-duty shoring posts. The mistake to avoid is standing a push-pull brace upright under a beam or slab because it adjusts and looks similar. Where the job carries weight, use adjustable steel shoring posts, with a U-head where a beam sits on top. Many jobs need both, with posts under the structure being carried and push-pull braces holding the walls and panels around it.
Post shoring for openings, slabs and panels
Openings in load-bearing masonry walls
Cutting a doorway or widening an opening in a load-bearing brick wall means holding up the masonry above until the new lintel is bedded. A PropMate support goes into a mortar joint above the line of the opening, an adjustable post goes beneath each one, and the wall rests on the posts while the brick below is cut out. One worker can set this up without needling through the wall or building scaffolding, which suits confined interiors and residential alterations.
Slab formwork and backshoring
Under an elevated slab, posts with U-heads carry the timber or steel beams that support the deck forms, and they take the full weight of wet concrete along with the crew and equipment working on it. After the forms are stripped, posts go back in as backshoring under the slab while it cures and the floors above are poured.
Tilt-up and precast panel bracing
Tilt-up and precast panels are stood with push-pull braces raking from the panel face down to the slab, and the braces stay in place until the roof structure or the permanent connections take over. The adjustment lets the erection crew bring each panel to plumb after it is set.
Remodeling and interior fit-out
During remodeling, adjustable posts hold up ceilings, floor joists and beams while a wall comes out or a structural member is replaced, and they brace the structure during selective demolition. Where the work runs through finished or occupied rooms, the floors and fixtures around the posts need temporary protection from dust and debris.
Shoring post sizes, heads and spacing
Height and size
Measure the clear height from the base to the underside of the load, allowing for any sole plate, U-head or beam in the stack, and choose the size whose adjustment range brackets that height with travel to spare at both ends. A post set close to full extension leaves no room to reach the load or take up settlement, and a post closed down to its minimum cannot be lowered to release it. The longest post available is rarely the right choice, because it is heavier to carry and may not close down far enough.
Fixed or adjustable U-head
Fixed U-heads suit repetitive work at a single level, such as a slab pour where every post stands at the same height and the beams run in straight lines. Adjustable U-heads add fine height adjustment at the head, which suits complex layouts, changing soffit levels and uneven ground where each post is trimmed on its own. Match the head width to the beam it holds.
Base and ground conditions
Each post needs a firm, level base. On soil, compacted fill or a suspended floor, a timber sole plate under the base plate spreads the load, and on finished floors the same plate protects the surface. A post should never stand on loose blocks, pallets or uneven packing.
Number and spacing of posts
How many posts a job needs and how far apart they stand come from the shoring layout drawn by the engineer, which accounts for the load, the post size and the beam spans.

Frequently Asked Questions
A shoring post is an adjustable steel column that temporarily carries a load from above, such as a ceiling, beam, slab or wall, while the permanent structure is built, altered or cured. The trade also calls it a post shore, a steel shore or a shoring jack post.
It depends on the post size and how far it is extended, because the safe working load of a telescopic post falls as it extends. Each product page carries the load figures for its sizes and fittings. The post is chosen so that it meets the load on the shoring layout at the height it will actually be set.
Mark the post positions from the shoring layout, set each base plate on its sole plate and stand the post plumb with a level. Set the rough height with the pin, fit the U-head or lintel support, and turn the collar until the head is tight against the load without forcing it upward. Check plumb again once every post is snug, and inspect the posts daily while they carry load.
The steel jack posts in this range are made for temporary support during construction and remodeling. A permanent basement column or beam support is a structural element designed to the local building code, normally a fixed steel column on its own footing. When the work is finished, the temporary post is replaced with the permanent column shown on the plans.
Both ends are fixed. The top attaches to the wall or panel, usually through inserts cast into a precast or tilt-up panel or with anchors drilled into an existing wall, and the foot attaches to the slab or a deadman with anchors. The anchor type, embedment and position come from the bracing design, and a brace that only leans against a panel gives no restraint against wind or pulling.
