Structural
Steel

Structural steel systems are engineering solutions with a wide range of applications, from industrial facilities and production buildings to maintenance platforms and conveyor galleries. The high load-bearing capacity and fabrication flexibility of steel offer a significant advantage on industrial projects, particularly where long spans must be bridged or where new equipment has to be connected to existing reinforced-concrete structures.

At Rayf Teknik, structural steel work is never treated as simply cutting and joining steel sections. The project's structural system, equipment loads, connection points, fabrication tolerances, erection sequence and site access are all assessed before work begins.

Integration with Industrial Structures

In cement plants, power generation facilities and tall reinforced-concrete industrial structures, structural steel often works hand in hand with the concrete structure. Silo roof platforms, chimney stairways, maintenance walkways, equipment supports and galleries can all be connected to reinforced-concrete structures by means of anchorages.

On projects where the silo or chimney shell is built with a slipform system, the structural steel connections need to be coordinated before reinforced-concrete work starts. If embedded plates and anchorage systems are set at the correct levels as the formwork rises, unnecessary breaking out, drilling and adaptation work during subsequent steel erection can be reduced.

Rayf Teknik's ability to deliver both slipform and structural steel work within the same project supports interdisciplinary coordination, particularly on industrial structures. Rather than the concrete team and the steel erection team working to separate design assumptions, the aim is to resolve connection details before execution begins.

During steel fabrication, material selection, cutting, hole preparation, welded connections and surface treatment must all be carried out in line with the project's technical requirements. Preparing components to match the erection sequence before they reach site is another factor that affects working time on tall structures.

On silo and chimney projects built by slipforming, most steel members are erected at high elevations. Assessing crane access, lifting points and erection platforms in advance therefore keeps the work programme running in a more orderly way.

Rayf Teknik's past references also include CEMS platforms and stairways for industrial chimneys, as well as a range of other industrial structural steel fabrications.

The aim of a structural steel project is not merely to produce a load-bearing system. The system must be designed with the personnel who will work on it, the equipment it will carry, the reinforced-concrete structure it will connect to and its long-term maintenance needs all in mind.

By combining structural steel with its slipform and reinforced-concrete experience in a single engineering approach, Rayf Teknik aims to develop fully compatible structural solutions for plants, silos, chimneys and other industrial facilities.
