To meet our customers’ full range of needs, we offer several services, including MTO products, call-out services, NDT certification, and more.

Made-to-Order Products

At GMI, we specialize in made-to-order flanges, fittings and other parts. We maintain a large, on-site raw material inventory and have quick access to specialty forgings through our vendor network. These advantages allow us to turn most custom orders around extremely quickly.

Contact us to find out how soon we can complete your order.

Call-Out Services

We are available around the clock. We’re in-shop 7:00am-4:00pm (CST), but a GMI employee is always on standby for after-hours requests. We can turnaround most call-out orders within hours. When it comes to urgent requests, our philosophy is to do whatever it takes to get it done as efficiently as possible. Call-out services are available to any customer, anywhere, from either our Houston or Broussard location. For orders and other needs outside of working hours, call 281.446.0093 or 337.369.1933.
