Will you derate one of your trailers?
Oct 8th
Will you derate one of your trailers from 9,760 pounds to say 9,000 pounds?
In compliance with NHTSA rules, we cannot de-rate any trailer for which we have published standard ratings. NHTSA believes that de-rating points to regulation avoidance, such as trying to avoid a CDL license requirement, or brake requirements in some states. If you have a specific trailer need or application you can contact a Diamond C rep at 800-827-3512 to figure out what options you might have.
American Made
Sep 22nd

All Diamond C Trailers are Made in USA. Since our origins in 1985, Diamond C has built quality American made trailers from our North East Texas manufacturing plant. We are a firm believer in supporting America, our economy, and industry. We employee a skilled American workforce and go above and beyond our countries standards to produce a higher quality product while maintaining a safe, clean, work environment. We utilize many American made trailer parts and components, and take pride in our partnerships with US companies such as Dexter Axles (who’s hubs, drums, and brakes are made right here in the USA.) and American chemical company DuPont (founded near Wilmington, Delaware, USA in 1802). We thank you for supporting our friends, family, and neighbors.
What is an EZ-lube axle, and why does it matter?
Sep 20th
All Diamond C Trailers come standard with top quality, brand name Dexter EZ-Lube axles. In short, Dexter’s EZ Lube Axles means bearing lubrication is quick and easy.
- No dis-assembly required, just attach a grease gun at the spindle end and inject the grease.
- EZ Lube cap allows for easy access, extra protection, and virtually no mess.
- Allows grease to easily flow to both the inner and outer bearings for a complete repack.
- Easily purges contaminated grease without removing the hub.
Dexter’s mission to provide quality running gear assemblies and related components with the highest level of customer service is an obvious match for Diamond C. We encourage you to send us your feedback, and let us know how Dexter Axle’s 40 years of experience is working out for you.

Diamond C Trailers and Aluma, KLM Combine Marketing Efforts to Better Service Dealers
Jul 23rd
Diamond C Trailers announces a strategic marketing agreement with Aluma, KLM that will provide North American Trailer Dealers with greater access to personalized service before, during, and after the sale. The agreement enables Aluma’s eight regionalized sales representatives to represent the Diamond C product line to both existing and prospective accounts in the U.S. and Canada.
“At the end of the day, successful business revolves around relationships,” said Jeffery Crabb, President of Diamond C. “As our market expands away from our Texas manufacturing facilities, we recognize the need to maintain personalized service so that every dealer feels like they are in our back yard. Aluma’s professional sales representatives will afford our dealers that opportunity.”
Mike Lloyd, President of Aluma, agrees, “This is a perfect match for our company. Diamond C’s reputation for quality and service in the industry closely matches that of Aluma.”
Both companies expect to gain synergies in reducing the fixed costs associated with outside sales travel. “The end result will be better service through quicker response times and tailor-made solutions without burdening the dealer with higher trailer prices to offset the sales investment.”

Founded in 1985 and headquartered in Mt. Pleasant, TX, Diamond C services dealer partners in over 100 locations throughout the U.S. and Canada. Dealers can choose from over 60 standard models with limitless customized options – making Diamond C one of the most diverse flat-bed manufacturers in the business. Diamond C commits itself to the progression of the trailer industry by continuously demonstrating excellent quality and value, cutting edge innovation, and superior customer service.

Founded in 1992 and headquartered in Bancroft, IA, Aluma services dealer partners in over 250 locations throughout the U.S. and Canada. Aluma produces the largest selection of flat bed, truck bed, and enclosed all aluminum trailers in the industry. Quality is the number one goal and is backed by an all inclusive 5 year warranty. Aluma has ensured the best service inside and out with full time inside sales people and 8 experienced sales people traveling the U.S. and Canada.
How does Diamond C’s paint finish compare to a powder coat finish?
Jan 24th
Powder coating definitely has its place in the world, but it’s not in utility trailers. Diamond C takes this position for the following reasons:
- Powder coating does not use primer. So when the finish on a powder coated trailer gets scratched or chipped which is almost inevitable with normal use, it’s down to bare steel and left with no protection from corrosion. And with no protection from corrosion remaining, the scratches and chips inevitably grow as the finish weathers, often times releasing from the trailer in large sections or sheets.
- Powder coat is difficult to match for touch ups. Away from the trailer factory, powder coat finishes are touched up with spray paint. Rarely does spray paint match the powder color, and it will not adhere to powder coat. Powder and spray paint do not mix.
- High quality paint finishes (including high quality primer) like what Diamond C uses are time tested by the auto industry. We use only industry leading paint/primer products that have proven superior and long-term corrosion resistance track records.
- Paint finishes are most easy to color match and touch up when necessary, most often done simply with an aerosol spray can.
