Steel Fabrication and Installation

PRECISION STEEL STAIR STRINGERS: THE FOUNDATION OF EVERY STEP

A staircase is more than just a way to move between floors; it is a vital part of a building’s structure and design. The stringers act as the backbone of the stairs, providing the strength and stability needed for thousands of footsteps over many years.

 At Hangan Steel, we specialize in creating high-quality steel stair stringers that offer a level of durability timber simply cannot match. We focus on absolute precision so that every step is perfectly level and secure. Whether you are looking for a sleek, modern look for a new home or a heavy-duty solution for a busy warehouse, our team ensures your stairs are built to last. We take pride in delivering steel supports that fit your space perfectly, making the installation process smooth and the finished result incredibly strong.

Expert Steel Stair Fabrication

Hangan Steel is the leading steel fabrication company melbourne builders choose for high-quality staircase components. We understand that a staircase must be both safe and visually appealing. That is why we focus on producing steel stair stringers victoria that meet strict building codes while looking fantastic. Unlike timber stringers, steel will not warp, shrink, or creak as the seasons change.

As experts in custom steel stairs melbourne, we provide a full service from the first digital drawing to the final delivery. Whether you need a single flight for a home renovation or complex multi-level stairs for an apartment building, we ensure the structural integrity of every riser and tread support.

Why Choose Structural Steel Stringers?

Using structural steel stringers offers several major advantages for Victorian construction projects.

Maximum Strength

teel can span longer distances than timber without needing extra middle supports. This allows for "floating" stair designs and open spaces underneath the staircase.

Durability

Steel is immune to termites and will not rot. This makes residential steel stairs victoria a smart long-term investment for any homeowner.

Total Precision

Using our CNC machinery, we cut every stringer to the exact millimeter. This ensures that every step height (the riser) and every step depth (the tread) is identical, which is essential for safety and comfort.

Versatile Design

Steel can be painted, powder-coated, or left with an industrial look to match any architectural style. Its flexibility allows it to blend seamlessly into modern homes, commercial buildings, and industrial spaces alike.

Custom Steel Stair Designs

Our steel stair fabrication melbourne facility can produce a variety of stringer styles to suit your specific building needs:

Single Stringer Stairs

A single, heavy-duty beam runs down the center of the stairs, creating a sleek and modern architectural feature. This style gives the stairs a clean “floating” appearance that is especially popular in high-end Melbourne homes, luxury apartments, and contemporary office spaces. Single stringer stairs also allow more natural light to flow through the area, helping rooms feel more open and spacious while maintaining exceptional structural strength and durability.

Double Stringer Stairs

This is the traditional stair design where two strong steel beams support the steps from both sides. Known for its outstanding stability and durability, it is commonly used for industrial stair stringers in factories, warehouses, commercial buildings, and high-traffic environments. Double stringer stairs are also a popular choice for residential projects because they offer a timeless appearance, excellent load-bearing capacity, and flexibility to suit both modern and classic staircase designs.

Zig-Zag (Sawtooth) Stringers

For a bold architectural statement, we can laser-cut stringers into a distinctive “sawtooth” shape that follows the exact profile of the steps. This removes the need for bulky side plates and creates a sharp, clean geometric finish that stands out in modern interiors and commercial spaces. Zig-zag stringers combine visual impact with structural precision, making them ideal for clients looking for a contemporary staircase design that blends style, craftsmanship, and functionality.

Protective Coatings for Stairways

Stairs are high-traffic areas, so the finish must be tough.

Powder Coating

We offer a wide range of colors for indoor stairs, providing a durable and attractive finish.

Hot-Dip Galvanizing

Essential for outdoor stairs or industrial sites, this protects the structural steel stringers from rust and weather damage.

Industrial Paint

A high-build primer and topcoat can be applied for a professional, clean look in commercial buildings.

TECHNICAL STANDARDS AND SAFETY

We had Hangan Steel conduct the supply and installation of our Structural Steel framework on the latest project we have underway in Lilydale. We had Peter put in charge of the works, which was scheduled, detailed, delivered and installed under his watch. He did a fantastic job, from the shop drawings to the well executed connections and perfect install. Very helpful and informative assisted with the expert advice from years of practical experience in the construction sector. Peter also went over and above... Even picking up some items that should have been my responsibility. He kept me informed with phone calls and photo's... You guys will be my first choice for my steel needs. Thank you Peter and Hangan Steel.

Indi and his team have been great to work with from start to finish on my steel gate project. When I needed to make adjustments they accommodated them easily with no issues. Mick arrived 15 minutes before our scheduled time which allowed us to go over the job with no rushing around. All work was super precise and finished neatly. Highly recommend for your next steel project.

From the office staff, to the production manager, to the people who came to site for the install, to the owner himself; I cannot fault this company for its integrity, customer service and above all the great job they did on what was a difficult and tight worksite. I would not hesitate to recommend them to anyone who is in need of structural steel of their next project.

The guys from Hangan Steel are very professional, organised and easy to deal with when getting structural steel works completed on my projects. Nothing is too hard and if I can say it the more technical the project the more the guys come to life in coming up with a positive solution for installing the steel. Highly recommend Indi and his awesome team.
