MatruOS for a hot-dip galvanising plant
Set up the way a hot-dip galvanising plant runs: galvanising charge per MT of steel (black weight) for fabricators' structures, tower members, solar mounting structures and fasteners; zinc is either inside the rate or charged as a surcharge linked to zinc price; sale of dross and ash to recyclers. Routines, workflows, registers, licences and an AI team that knows the work are ready when you sign up.

What this solves
What a hot-dip galvanising plant deals with today, and what MatruOS sets up for it
Today
Zinc consumption per MT drifts from 60 to 80+ kg and nobody sees it until the month's zinc bill. Zinc price rises between buying and billing; rates quoted for months without a zinc clause.
In MatruOS
MatruOS sets up 8 routines, 1 workflow, 4 registers and 11 licences for a hot-dip galvanising plant, with an AI team that reads your own records and prepares the work.
What changes
The right person is reminded at the right time, approvals wait for whoever decides, and every licence has a renewal reminder. Anything that sends, pays, signs, files or deletes waits for a person's approval.
Where you sit
MatruOS starts from how your business earns
Who you sell to, who you buy from, how credit moves and where you sit in the chain decide how your screens, reminders and reports are set up.

Your suppliers
- Zinc ingot dealers (primary SHG zinc)
- Hydrochloric acid suppliers
- Flux chemical suppliers
- LPG, natural gas or furnace oil suppliers
- Authorised hazardous waste recyclers and TSDF
Credit and cash
Zinc: advance or 7 days at the day's price; acid on 15 days; fabricators pay 30-60 days; EPC-linked jobs 60-90 days; small fasteners walk-in cash
Zinc is bought in cash every week (25-60 MT a month for a small plant); customers pay 30-60 days later. A zinc price rise between purchase and billing eats the margin unless the rate carries a zinc clause.
