List of Top Fabrication Materials to Use in the Construction Industry Today (2022)

The Architecture, Engineering, and Construction (AEC) industry is undergoing a technological revolution and will soon see a complete digital transformation - from concept to fabrication. Emerging trends like BIM and computational design will soon lead the way for computationally assisted design, automated manufacture, and assembly of buildings. While fabrication processes in the world of manufacturing like metal fabrication, steel fabrication, and wood fabrication have uses in the AEC industry even today, we will soon see the benefits of digital pre-fabrication and modular mass production of buildings like houses, offices, and hotels.

Fabrication material choice is extremely important when fabricating the desired forms for your building. In this article, we will explore what fabrication is, the types of fabrication processes, some points that you should keep in mind when selecting your fabrication material, and a list of some of the best fabrication materials in the market today.

What is Fabrication?

In the simplest terms, fabricating a part or product means making it from scratch using raw or semi-finished materials. The process can include designing, stamping, welding, cutting, bending, and assembling. These processes can either be done manually or optimised with the use of Computer-aided Drawing (CAD) that can be programmed into CNC technologies.
These days, fabrication involves making components for items such as engines, machines, tools, building systems, and household appliances using materials such as metal, laminates, wood, steel, and other solid surface materials.

The different types of fabrication used in the construction industry include:


Structural steel fabrication: It is a process of bending, cutting, and moulding steel structures to create beams, columns, and steel members.
Metal fabrication: The method involves different techniques to modify raw metal into a new metal product. For construction, manufactured metals can be reinforcement bars, metal sheets, bolts, nuts, anchors, and metal tubings. Other than this, plumbing systems, drainage systems, and HVAC systems also use metal fabrication.
Plastic fabrication: Today, plastic fabrication is popular among manufacturers because of its two main properties, i.e., malleability and cost-effectiveness.
Digital fabrication: Unlike the others on the list, digital fabrication refers to a process of fabrication - rather than the material. Connecting building design to digital fabrication has the potential to change the game, with automated cutting and configuration systems to enable customers’ design choices to be fed directly into the production system. Architecture firms like Foster + Partners, Zaha Hadid Architects, and Frank O Gehry have turned to shipbuilders and their CAD systems and processes to fabricate large-scale components for buildings.

Key Points when selecting Fabrication Material

When choosing the perfect fabrication material, you should consider the end-product which you’re aiming for and the process involved in achieving that. Other factors that you should consider include:
  • Cost of the material,
  • The durability of the material,
  • Availability of the material,
  • How you want the finished product to function
  • Fabrication timeline,

Finding the perfect fabrication material can therefore be overwhelming unless you know exactly what you’re looking for. Here’s a list to ease your decision process.

List of Fabrication Materials to use in the Construction Industry Today

1. Iron

Iron fabrication’s use in the AEC industry is more industrial than ornamental. Examples of its usage include iron railing for staircases, ductwork, stacks or silos, iron rods, etc. Manipulating iron includes processes like bending, forming, rolling, cutting, and punching.


Pros: The advantages of using iron include its long-lasting durability, excellent machinability, and resistance to deformation.
Cons: The main disadvantage of using this fabrication material would be its heavy weight. Another one would be that the material is prone to rust and eventually gets harmed by continued rusting.

2. Steel

Steel rods

Steel is an alloy of iron and carbon (the higher the carbon content, the stronger the steel). The material is used throughout the Industry, from transportation appliances to mega-structures to entire buildings!
Some examples include bar joists, ladders, grating, skids, universal beams, universal columns, industrial equipment, etc. The steel fabrication process can be broken down into three parts – melting raw materials, mixing melted materials into steel, and forming the desired shape using said steel.


Pros: There are various advantages of using steel for your AEC projects. Some of them include its reliability, industrial behaviour, faster construction, and its elasticity.
Cons: The major disadvantage of using steel is its high maintenance cost.

3. Sheet Metal
