Shutdown windows
What sets the size of the crew
No two windows are alike. Four things decide how many people we send and for how many shifts.
Hours in the window
A forty-hour weekend and a three-week turnaround need different crews.
Start and end, to the hour
Whether days, nights or both
Steel area and prep grade
Square feet or tons, and the cleaning grade the spec asks for.
Drawings or a measured walk-down
Existing coating, sampled
Access
Lifts, scaffold, rope access and the lanes to reach them.
Where equipment can stand
Permits and lockout steps
Weather exposure
Open steel loses days to wind and cold. Enclosed steel doesn't.
Spray limits for wind and surface temperature
Weather days in the schedule
Shifts
Day crew or night crew
Both work. Which fits depends on your site and the season.
Night shift
Heat
Cooler steel; often the summer choice
Light
Portable lighting and a night supervisor
Your staff
A named contact on call
Neighbors
Quieter roads and yards
Day shift
Heat
Steel can run too hot to coat in summer
Light
Daylight
Your staff
Your maintenance team is on site to answer
Neighbors
Shared traffic with the plant
Weather rules
When the coating says stop
Coatings have limits printed on the data sheet. We read them before the shift, not after the run.
Surface temperature
Too hot and the film dries wrong. Too cold and it won't cure. We check with a gauge at the start of each shift.
Dew point
The steel has to stay a few degrees above the dew point while we spray and while the coat cures.
Wind
A gusty day throws overspray off the steel. The plan sets a wind limit and we hold to it.
Tell us the window.
Dates, hours and the steel. We'll say what fits and what it takes.
