Our mission
COF’s Mission is to work in partnership with our customers, while relentlessly pursuing excellence and exceeding expectations in terms of safety, quality, schedule, and value.
Our values
Safety
CUST-O-FAB takes a people-first approach to safety. We train our employees to always keep in mind the lives that will be affected by the safety of a job. At the end of the day, it’s always about respecting and protecting the lives of our crew and our customers.
Quality
Quality permeates the entirety of CUST-O-FAB’s culture. We hire the best to give our customers the best, and we strengthen our team through ongoing training and mentorship so we remain the best equipment and service provider in the industry.
Schedule
Experience has given us the tools to maximize efficiency. Our customers depend on strict schedules, and we know wasted time is wasted money. Over five decades we’ve continuously improved our processes to deliver in the shortest time possible.
Value
Value goes beyond the bottom line. True value is only possible when a job is safe, quality-driven, and on schedule. We never cut corners, because poor safety or quality ends in unplanned shutdowns, disrupted schedules, and budget overages.
