The staircase is used more than nearly any other part of a building day after day for decades, without given a thought by who walks up and down it. This is what it is all about. When a precast staircase performs its function, no one is aware of it. When it’s not working out, it’s typically because the owners select the wrong manufacturer. This guide will give you all the information you need to know about how to select the best precast concrete staircase manufacturer in UAE.
What Manufacturers Can Offer Is More Important Than the Design of the Staircase
Each staircase seems simple on the floor plan: risers and treads and a landing. But here, as in most things, precision is key; stairs that are even slightly misplaced in riser height or tread depth become a real safety hazard rather than an aesthetic issue. The configuration of each project includes the floor-to-floor height, dimensions of the tread and landing and they must be exact, flight by flight, floor by floor.
It is of this sort that a manufacturer with a real engineering department deals routinely. Without one, a manufacturer is flying blind when it comes to your project’s particular size.
The First Step Is to Ensure That They Are Certified to Operate in the Area
For any project located in Dubai, this is a must-do task. Dubai Municipality has a specific law pertaining to the production of precast staircases. Dubai Municipality issued Administrative Decision No. 316 of 2012 in order to regulate ready-mix concrete plants, precast concrete factories, and central batching units. Manufacturers operating in the emirate must adhere to these approved rules and specifications.
Directly inquire if your manufacturer has a Certificate of Product Conformity under this framework and specifically under Dubai Municipality’s technical specification DMS 026. A supplier who is not afraid to create this documentation has an understanding of the regulatory environment that they are working in. If a supplier breezes past the question it is a sign that they are implying you’ll take their word for it when it comes to compliance.
If your project is in Abu Dhabi, inquire about similar oversight instead. Oil and gas and civil infrastructure suppliers to the emirate commonly have ISO 9001:2015 accredited quality systems that cover manufacturing to standards defined by Abu Dhabi General Engineering Specifications and Abu Dhabi Municipality specifications for industrial and civil projects.
Test Their Concrete Mix and Strength Standards Precast Concrete Staircase Manufacturer
The concrete strength is not something that can be overlooked with precast staircases, as they are constantly used for foot traffic. The minimum 28-day compressive strength of precast concrete stairs is 5,000 psi, and the cement used should be in accordance with the recognized standards, with no use of chloride-based admixtures that could promote the corrosion of the embedded steel over time.
Inquire about the compressive strength of your manufacturer’s expectations and the curing process they use. Only the most reputable specifications call for form curing by moisture retention until when the concrete is strong enough to be removed, usually at least 2,500 psi before the units ever are removed from the form. If these numbers are available in a manufacturer’s quotation, then the manufacturer has built to a real specification and not to the standard concrete specification.
Ask Them How They Cope with the Heat in Dubai During Production
Gulf summers make an authentic manufacturing problem, one that other manufacturers never have to solve. The maximum concrete placement temperature is specified as 35°C by Dubai Municipality itself, and the manufacturers ensure this in a variety of ways, including the addition of flaked ice to the water, the use of chillers to cool the mixing water and the use of light-colored paint on plant equipment to minimize heat absorption.
This detail is important due to the fact that concrete poured too hot will cure unevenly and become weak over time, which may not be evident on day one, but will be evident in time. Find out from your manufacturer how they are able to control placement temperature in their summer production schedule. If they didn’t think about it, your stairs are likely to have been poured in an environment that wasn’t ideal.
Check Their Reinforcement and Handling Standards Precast Concrete Staircase Manufacturer
Proper handling provisions at the casting stage are necessary to ensure that a precast staircase can withstand being lifted, transported and installed before it is used for the first time. Recognized specifications indicate that manufacturers must place and secure all anchors, lifting devices, shear ties and other handling hardware directly into the forms during the casting process, as well as the reinforcing steel required.
Exposed edges must be sharp, straight and square with flat surfaces cast true, because over the years the exposed edges become an aesthetic concern and potential tripping hazard. See a sample unit or site photos for edge quality before placing large orders.
Examine Their Engineering and Erection Capability Precast Concrete Staircase Manufacturer
The construction of the staircase is only half the work if it is made improperly. The other half—correct installation—should be scrutinized as well. Qualified and experienced erectors of precast structural concrete of similar magnitude and/or duration to erection of the project in question are recognized as industry standards and are engaged for an appropriate period of time to erect precast structural concrete. A registered structural engineer must certify that erection conforms to the design requirements.
Inquire with your manufacturer whether they perform the installation themselves or if they subcontract it, and how long their erection team has been carrying out this type of work. A manufacturer who pushes installation to the back of the list is giving the job to whomever is available that week.
Compare Their Scale and Facility Standards
When executed correctly, the production of precast stairs is a sizeable operation in a workshop. The leading manufacturers in the UAE have large and modern factories with engineering departments capable of dealing with complex staircase structures of any size. For instance, there is a dedicated precast plant producing structural and architectural precast systems, including staircases, in Dubai Investments Park, Dubai, UAE.
Such scale typically translates into more consistent processes throughout large contracts, as all of the units are produced on a controlled production line rather than varying from batch to batch.
Recognize the Red Flags Precast Concrete Staircase Manufacturer
Some red flags keep reappearing with less reputable precast staircase suppliers. Look out for non-conforming Dubai Municipality certificates or certificates from another body, answers that are not specific and detailed (such as concrete strength or curing process), no clear response about how they cope with summer heat during concrete production, and no examples of projects where they have erected concrete staircases of a similar scale.
None of these individually should automatically disqualify a manufacturer. However, if two or three appear together, it’s a clear indication to ask more questions before signing any agreement.
Bringing It All Together Precast Concrete Staircase Manufacturer
The selection of a precast concrete staircase manufacturer in the UAE hinges on a few key factors:
- Ensure they are regulated by Dubai Municipality or a similar authority.
- Verify their concrete strength and curing procedures.
- Inquire about their measures for working in extreme heat conditions.
- Assess their reinforcement, handling, and erection expertise in light of the project’s size.
If you skip these checks, then you’re relying on one of the most heavily used parts of your building’s infrastructure on a supplier that hasn’t proved their process. Do it right, and your staircase will do exactly what it’s supposed to do: safely and silently carry foot traffic flight after flight, as long as the building endures.
