what we do

Our Services

Collaboration with customers at this early phase helps all parties understand all the options available and their consequences, and to align expectations. Al-Ayash’s pre-construction services help customers lay the groundwork for a highly successful project. Our experience and insights mean we’re able to see a project from a “big picture” perspective, and to identify even the smallest details that could impact a project.

Our contributions help make the design and building process more effective with preliminary technical information, planning and scheduling, and budgetary pricing.

Complex needs and challenges don’t stand in the way of our engineers and designers. We take advantage of impressive state-of-the-art technologies. This efficiency saves customers significant time and money.

Tank designs are based on various industry standards including but not limited to:

  • API (American Petroleum Institute)
  • AWWA (American Water Works Association)
  • NFPA (National Fire Protection Association)
  • AWS (American Welding Society)
  • ASTM (American Society for Testing Materials)
  • ANSI (American National Steel Institute)
  • ASME (American Society of Mechanical Engineers)
  • UL-58 (Steel Underground Tank for Flammable & Combustible Liquids)
  • UL-142 (Steel Above Ground Tanks for Flammable & Combustible Liquids)

AL-AYASH field construction methods are state-of-the-art in both process and safety. Our teams are made up of long-term, permanent employees who know tanks inside and out, and are committed to safe, successful projects. Al-Ayash crews have the insights and agility to work with customers and site owners in a way that eliminates disruption to the workflow and helps ensure optimum productivity.

Our Wheelabrator (blasting machine) and environmentally controlled paint booth allow us to perform a critical step in the fabrication & construction process, in house under strict quality control guidelines.


  • Our Wheelabrator allows us to blast each piece of plate material to a blast profile that exceeds all required standards for both interior and exterior surfaces
  • Blasting removes mill scale, providing optimal surfaces for exterior field painting and reduces the need for interior blasting in the field

Environmentally Controlled Paint Booth

  • Our in house environmentally controlled paint booth provides ideal conditions for priming plate material, with no delays due to weather conditions. Plate material arrives on site protected with primer and ready for exterior paint and interior coatings systems
  • In house blasting & priming capabilities contribute to tighter schedules, efficiency in construction and overall lower costs

Field Blasting & Coatings

We provide field blasting &coating services with our own painting division. Exterior tank painting can be performed of tank fabrication and construction, or as part of a maintenance and repair projects.

Tank painting projects are planned and executed using the highest quality coatings systems as dictated by the tank’s purpose, location and contents.
