Engineered Prefab Steel Buildings for Speed, Strength, and Flexibility
Overview
STEELInfra™ Prefab Modular Steel Buildings are factory-built steel structures with insulated wall and roof systems, designed for rapid deployment, rooftop extensions, and permanent or semi-permanent applications.
Backed by Teleios’ proven Pre-Engineered Building (PEB) expertise, our prefab buildings deliver faster construction, lighter structural weight, and predictable quality—making them ideal where time, space, and site conditions are critical.
Unlike conventional RCC construction, STEELInfra™ prefab buildings are manufactured in a controlled factory environment and assembled on-site with minimal wet work, reducing construction time, disruption, and uncertainty.
Applications of STEELInfra™ Prefab Buildings
Our prefab modular steel buildings are widely used across industrial, institutional, and commercial sectors, including:
- Sales & marketing offices
- Hospitals, healthcare blocks & medical extensions
- Exhibition halls & experience centres
- Site offices & administrative buildings
- Rooftop building extensions
- Institutional, training & classroom facilities
- Command, control & operations centres
- Car Showrooms and service centres
- Highway Restaurants and Rest Areas
Depending on design intent, these prefab buildings can be temporary, semi-permanent, or permanent in nature.
What We Deliver
- Engineered Prefab Shell
A fully engineered, weather-tight prefab steel building envelope.
Includes:
- Primary steel structure
- PUF insulated wall and roof panels
- Doors, windows, and external closures
- Designed for strength, speed, and durability
Suitable where interiors are executed by other agencies.
- Interface-Ready Prefab Shell (Recommended)
A value-added prefab shell designed to simplify interior and MEP works.
Includes everything in Engineered Prefab Shell, plus:
- Pre-planned electrical, plumbing, and HVAC routing zones
- Partition-ready wall design
- Ceiling-ready structural layout
- Defined wet-area and service zones
This reduces site coordination issues and accelerates fit-out timelines.
- Turnkey Prefab Buildings (via Empanelled Partners)
For clients seeking a single coordinated solution, Teleios can deliver prefab buildings with interiors and MEP works executed through approved partner agencies, with integrated design coordination.
Construction System & Material Specifications
STEELInfra™ Prefab Modular Steel Buildings are engineered using proven construction systems and material options, allowing flexibility based on functional, aesthetic, and budget requirements.
Structural System
- Load-bearing columns and beams:
High-quality structural steel, designed and fabricated as per applicable codes to ensure strength, safety, and durability.
Floor System
- Floor:
5-inch reinforced concrete slab cast over profiled decking sheets, providing structural rigidity, durability, and compatibility with standard floor finishes.
Ceiling Options
- Ceiling:
- Exposed decking sheet with protective paint finish, or
False ceiling systems as per functional and aesthetic requirements
Wall Systems
External Walls (configurable options):
- PUF (Puff) insulated panels
- Brick masonry
- Glass glazing systems
- Cement sandwich boards
Internal Partition Walls (configurable options):
- PUF (Puff) panels
- Brick masonry
- Aluminium–glass partitions
- Cement sandwich boards
Wall systems can be selected based on insulation, fire-rating, durability, and usage requirements.
Roofing System
- Roof:
PUF (Puff) insulated roof panels, providing thermal insulation, weather protection, and long-term performance.
Wet Areas
- Wet area construction (toilets, kitchens, pantries):
- Brick-lined construction, or
- Cement board–lined construction
Designed to ensure durability, moisture resistance, and compatibility with plumbing and waterproofing systems.
