There are many challenges in making custom stairs as certain measurements have to be made or kept in mind before creating spiral around steel tank. One of the challenges is measuring the curvature of the stair stingers which is two part steel structure that holds the stair threads together. The stingers must be put together carefully in exact matching curvature perpendicular to the first curve in the arc that is located at precise height at the right exact position in the tank.
Below is the diagram of spiral steel rail which was built by us and custom measurements were carefully taken. There are different standards for making spiral rails and if rest platforms which are intermediate levels are present then computations start again from the platform level which goes on to the next level. Meticulous care must be taken to check and see if all the substructures must fit in together and maintains the aesthetic sense and beauty. Since we have more than 10 years’ experience making these custom rails, we at Al Ameen Engineering are frequently called on to check and correct the installations of handrails, ladders and platforms and we usually advice clients to do their due diligence on the steel fabricator before handing out the contract.
We then use top state of art engineering software to check if all calculations and assumptions made in fabrications are right and ensure every component fits the specifications and fits together as it is supposed to. We have different designs and specifications of the staircases the clients can check before ordering. We have made many spiral staircases for government buildings, villas and many commercial buildings in the region.
