Triangular Scaffold | Omega Shoring System for Slabs, Beams and Bridge Decks

Triangular scaffold, also called omega scaffold or omega shoring, is a modular load-bearing system used for slab formwork, heavy beams, concrete decks and temporary vertical support. Alborz Ghaleb manufactures and supplies triangular frames, diagonal braces, adjustable U-head jacks and base plates from Karaj, Iran, with local and export delivery. Direct answer: omega shoring is a fast-assembly modular scaffold system designed mainly for vertical load support, not just worker access. For contractors who need safe support under concrete slabs, bridge decks and heavy formwork, it is usually more efficient than traditional tube scaffolding. Catalog PDF DownloadCall sales

What Is Triangular Scaffold and Why Is It Called Shoring?

Shoring scaffold is a temporary support system designed to carry vertical construction loads until the permanent concrete element reaches the required strength. Triangular scaffold works as a shoring system because its main job is to support slab formwork, beams, bridge decks and heavy temporary loads. The system is built from pre-fabricated triangular frames that stack vertically and lock together with male/female connectors. Horizontal and diagonal braces create a stable grid. The triangular geometry helps distribute forces efficiently and reduce lateral deformation during concrete placement. In export markets, the product may be described as triangular scaffold, omega scaffold, omega shoring, modular shoring tower or slab shoring frame. The names vary, but the technical purpose is the same: a fast, reusable and stable vertical load support system.

“When choosing shoring, the unit price of the frame is only one part of the decision. Base condition, bracing, jack adjustment and load sequence determine how safely the system performs on concrete-pouring day.” — M. Dashtabadi, Technical R&D Manager, Alborz Ghaleb, July 2026

Key Benefits of Triangular Scaffold

• Fast assembly: male/female connectors reduce the need for many clamps, bolts and hand tools.
• High vertical load support: triangular geometry and bracing make it suitable for slab and bridge deck shoring.
• Precise height control: 0.5 m, 0.75 m and 1 m frames work with adjustable U-head jacks for final leveling.
• Lower labour cost: repetitive modular components reduce installation complexity and crew training time.
• Reusable investment: frames can be used across multiple projects when cleaned, inspected and stored properly.
• New and used supply: contractors can choose factory-new equipment or inspected used frames depending on budget.
• Organized transport: pre-made frames stack and ship efficiently for domestic or export projects.

Modular triangular scaffold is best when the main requirement is vertical load support. If the project is primarily façade access, complex platform geometry or many working levels, cuplock or ringlock scaffolding may be more flexible.

Parts and Technical Specifications

For heavy projects, the frame spacing and bracing arrangement must be checked by the project engineer. General scaffold safety resources such as OSHA Scaffolding and HSE scaffolding guidance are useful references for safe planning.

Triangular Scaffold Price Factors

Triangular scaffold price depends on real frame weight, tube diameter, tube wall thickness, coating, weld quality, new or used condition, brace and jack quantity, order volume and delivery route. Because steel prices change frequently, a live quotation is recommended before purchase.

• The 1 m frame usually has the largest share in total weight and cost.
• Bulk orders reduce transport cost per unit and make production planning easier.
• Used frames can reduce initial cost when they are straight, clean and structurally sound.
• Export orders need packing list, gross weight and spare pins or braces.

For a realistic quotation, do not compare only the price of one frame. A complete omega scaffold system includes frames, braces, U-head jacks, base plates, pins, packing and transport. If any of these items is missing, the site may stop on concrete-pouring day even when the main frames are available.

How to Estimate Quantity for a Shoring Project

Start with the slab or bridge deck area, then check the clear shoring height. If the grid is designed around 120×120 cm, each triangular scaffold frame bay covers roughly 1.44 m². This number is only a first estimate. Openings, drop beams, ramps, column zones and different slab thicknesses change the final layout. A safe slab shoring system is calculated with load, height, bracing and ground support together. Reducing the number of frames only to save cost may increase settlement risk, local overload or deformation under fresh concrete. The cost of a few extra frames is usually lower than the cost of a delayed concrete pour. For industrial slabs, bridge decks and heavy beams, the frame spacing may need to be reduced and the bracing pattern increased. Alborz Ghaleb can review a drawing or item list and prepare a practical frame, brace and jack estimate before issuing a proforma invoice.

Production and Quality Control

Omega scaffold production starts with selecting suitable steel tube. Tube diameter and wall thickness affect the real weight of each frame and the long-term durability of the system. After cutting, components are positioned in fixtures so the frame geometry remains consistent across the production batch. Joints are welded using CO2 welding. In a load-bearing shoring frame, weld quality is critical because connector zones and tube intersections transfer repeated loads. Before painting, the frame should be checked for straightness, connector looseness, visible weld defects, pin hole quality and surface damage. CO2 weld quality should be continuous and free from cracks or voids. For used frames, the same inspection is important: a frame can look acceptable from a distance but still have deep corrosion, bent connectors or damaged pin holes. Factory inspection and buyer-side visual checking reduce this risk.

Export Packing and Delivery

Export shoring frames must be packed and counted carefully. For Iraq, Armenia, Russia, Türkiye or GCC deliveries, the buyer should receive the number of frames, braces, jacks, base plates and spare connectors in a clear packing list. Gross weight and loading method should be known before dispatch. For export projects, it is practical to add 3-5% spare pins, braces and a few replacement frames. The cost of spare parts is small compared with the cost of waiting for missing components at a foreign jobsite. Alborz Ghaleb can coordinate packing, counting and loading support for bulk triangular scaffold orders.

How to Install Triangular Scaffold Step by Step

HowTo summary: prepare the ground, place the base frames, install horizontal and diagonal braces, build upward in levels, set U-head jacks, inspect the system and dismantle safely from top to bottom.

1. Prepare the base. The ground must be compact, level and able to carry the load. Use base plates on soft or uneven surfaces.
2. Place the first row. Set the base frames on marked grid lines, commonly around 120×120 cm spacing unless engineering design requires otherwise.
3. Install braces. Add horizontal and diagonal braces immediately to stabilize the first level.
4. Build upward. Add upper frames level by level and complete bracing at every stage.
5. Adjust U-head jacks. Set the final height under beams, slabs or formwork support members.
6. Final inspection. Check connectors, braces, base settlement and top level before concrete placement.
7. Controlled concrete pour. Avoid sudden and asymmetric loading in one area.
8. Dismantle safely. Remove components from top to bottom after technical approval.

“The final inspection before concrete placement is more important than assembly speed. Once concrete pouring starts, correcting a weak brace or open joint becomes expensive.” — Alborz Ghaleb Technical Team
