Frequently Asked Questions
Why choose a steel box?
Because sites destroy things.
It takes impact without shattering.
It deforms rather than breaking open.
It keeps working afterwards.
Nothing else handles abuse as well.
What has to be bonded, and how thoroughly?
Every conductive part, reliably.
Body, lid, gland plate and door.
A hinge is not an earth path.
Neither is a painted joint.
Straps do the job hinges cannot.
What happens if the bonding fails?
The box itself becomes the hazard.
A fault energises the shell.
Somebody picks it up next.
Protection may never operate.
That is the whole risk of a conductive enclosure.
Does it corrode?
Wherever the finish gets chipped.
Handling causes the chips.
Rust starts there.
Galvanised surfaces last much longer.
Stainless fixings avoid seized screws.
Is the weight a real disadvantage?
On a ladder or a scaffold, yes.
It is a two-person lift sooner.
Mounting needs more thought.
On the ground it barely matters.
At height it decides the choice.
Can a damaged box be repaired?
Often, which is part of its appeal.
Dents can be worked out.
Hinges and catches are replaceable.
Welding is possible where plastic is not.
Bonding must be proven again afterwards.
Where does steel win outright?
Heavy civil and industrial sites.
Moving plant nearby.
Hot work and sparks around.
High mechanical risk generally.
And anywhere rental fleets are used hard.
