Made-In-Melbourne. Since 1969
We’ve been making things that last — right here in Melbourne — since 1969.
From our beginnings as a small metalworking business, we’ve grown into a family-owned group manufacturing steel and timber solutions under one roof — supporting schools, workplaces, and public facilities across Australia and New Zealand.
Across every brand, our focus remains the same: practical design, reliable manufacturing, and products built to last — backed by a family-owned business that values long-term relationships
School Lockers Buyers Guide
We’ve learned a lot from building school lockers tough enough to handle the daily reality of school life — from teenagers to younger students.
This practical guide will help you choose the right lockers for your campus with confidence. It breaks down the key decisions — materials, sizing, locks, layouts and finishes — so you can plan with clarity.
And when you’re ready, we’re here to support you with design, specification and insight that fits what your school needs.
Here are our top take-aways
- Use full-length piano hinges for strength and longevity.
- Size lockers to fit backpacks, jackets, books, devices and sports kit — not just textbooks.
- Choose simple, intuitive locks that work for everyone — reliably, every day.
- Steel is unmatched for strength and long-term durability, and with powder-coat colour options, graphic perforations and acoustic lining inserts, it’s now become the design-led favourite too.
- Add sloping tops for weather ouside— and inside, to prevent dust build-up and items being stacked on top in busy corridors.
Solving Problems Is Our Thing
We make things that last.
Products that fit exactly where you need them to fit, and do exactly what you need them to do.
Our products support important work in education, emergency services, transport, recreation, on infrastructure projects and in the corporate sector – sometimes critical and hazardous work.
Let us know what you need, we’ll problem solve it, and come back to you with a product that gets the job done.
Products that do exactly what you need them to do
Case Study: Ambulance Victoria
Ambulance Victoria needed a secure, durable linen storage system that could withstand constant emergency-department use — while supporting real-time inventory visibility.
Stronghold manufactured and supplied custom steel locker banks designed for heavy-use healthcare environments, integrating seamlessly with RFID-based linen tracking.
The result: dependable access to critical supplies, reduced stock uncertainty, and infrastructure that simply works under pressure.

What our clients say
We’re still using the Stronghold lockers we installed more than ten years ago.
We thought our design was all set, but Stronghold suggested some practical changes that made it better.
Stronghold have been building our custom cabinets for us since 2001.
They supply our custom components to us every month - on time & exactly to spec.
Case Study: Museum Victoria
Museum Victoria needed to significantly increase cloakroom storage capacity while maintaining smooth visitor flow and daily locker availability.
Stronghold manufactured custom steel locker banks with electronic access control, designed to maximise locker density, withstand heavy public use, and automatically reset overnight.
The result: reliable, high-turnover visitor storage that remains available day after day without staff intervention.
