Joining Solutions for Electrical, Plumbing & Metalwork

A good joint is only as strong as the materials and preparation behind it. At Industrial Shed, we stock a complete range of solder & flux solutions designed for electrical, plumbing, roofing, HVAC & metal fabrication work.
Solder provides the mechanical strength & conductivity needed to bond metals, while flux ensures clean surfaces & smooth solder flow by removing oxides & preventing reoxidation during heating. Whether you’re wiring delicate PCBs, sealing copper plumbing systems, or tinning sheet metal for roofing repairs, our range has the right alloy, diameter & flux formula for the job.
We carry rosin-core, lead-free, acid-core, silver-bearing & plumbing-grade solder, as well as flux paste, gel & liquid formulations to suit different applications & base metals.

What’s in This Collection:
► Lead-free solder: for electronics & environmentally conscious work
► Rosin-core solder: for circuit boards, wiring & fine electronics repair
► Plumbing solder & acid flux: for copper & brass pipework
► Flux paste, gel & liquid: for improved adhesion & wetting
► High-temperature solder alloys: for HVAC, roofing & metal fabrication

Frequently Asked Questions

What’s the difference between rosin-core & acid-core solder?

Rosin-core solder is designed for electrical work & leaves minimal, non-corrosive residue. Acid-core solder is more aggressive & is used for plumbing or metal repairs—never for electronics.

Do I need extra flux when using rosin-core solder?

Usually no, as rosin-core solder contains built-in flux. However, on oxidised or challenging joints, extra flux can still improve wetting & adhesion.

Can plumbing solder be used on electronics?

No. Plumbing solder often contains acid-based flux that can damage electronic components. Use electrical-grade rosin-core or lead-free solder instead.
