Our new duo of CAR HAULERS have cleverly designed storage options to keep all your tools, tie-downs, and other accessories safe and secure while your are transporting your vehicles.

V-Tongue Storage Lid

We’ve brought our popular HD V-TONGUE storage lid design from our Equipment trailers over to our 2021 series of Car Haulers. This intelligently crafted lid design offers maximum storage space for jacks, tools, and straps, while also doubling as bonus deck space. This area also boasts a winch mounting plate as standard equipment.

This 19″ lid comes standard on model GTF, and the bumper pull version of the larger MVC multi-car hauler includes the full size lid as standard.

Extraordinary Trailer Finishes

While many trailer manufacturers choose powder coat and finish processes based solely on their material and operating costs, we designed this “Difference Maker” Powder Coating System to produce extraordinary trailer finishes.

The mantra is simple: Improve everything. Sacrifice nothing.

These are the priorities:
– Adhesion
– Corrosion resistance
– Chip & abrasion resistance
– Gloss & color retention
– Curb appeal

We’ve spared no effort or expense to ensure that each Diamond C trailer comes with an extraordinary finish that is exceptionally durable and beautiful.

We’ve partnered with Sherwin Williams to bring more enhanced color options, and are proud to offer multiple standard & special colors to choose from. View our comprehensive COLOR GUIDE to see all of our standard and custom colors up close.

COLOR GUIDE

How Does it Work?

Listen in as Jacob walks you through the entire powder coat process, start to finish:

For a detailed in-depth guide and to see the entire powder coating facility up close, be sure to watch the following videos for a deep dive into all things DM Coating System, as well as a comprehensive conversation on the differences between custom, small-batch coating vs. industrial coating.

The Powder Coat Process

We use a 6 step process to ensure our custom trailer powder coating is the best coating option for your trailer:

Step 1:

Each trailer frame is blasted with steel shot to remove mil-scale and add an anchor profile for primer to adhere to.

Step 2:

Then we wash them with a 5 stage wash process to clean the steel, add corrosion resistance, and balance pH.

  1. Alkaline wash removes blast dust and oils
  2. High pressure rinse
  3. Phosphate salt rinse inhibits rust and helps with paint adhesion
  4. High pressure rinse
  5. Final sealing rinse is applied

All wash water is reverse osmosis (RO) purified to ensure consistency

Step 3:

Washed frames are promptly force dried as they travel through our dry-off oven at 300 degrees. This prevents flash rusting and ensures that frames are primer ready.

Step 4:

Ultra-corrosion resistant Onecure Zinc Epoxy Primer powder coating is electrostatically applied to the entire trailer frame.

Step 5:

Smooth, high gloss, Onecure Technology Top Coat is electrostatically applied to the entire trailer frame.

Step 6:

The top coat is cured as the frame travels through our 165′ final-cure oven at 450 degrees. All steel surpasses 425 degrees to ensure complete curing of primer and top coat.

Differentiators

  • Pretreatment. Some powder coaters only blast. Some only wash. Some do a little of each. Every trailer that we powder coat is thoroughly blasted, washed clean, and chemically pretreated before powder application to ensure optimal surfaces for powder adhesion and corrosion resistance.
  • Powder. All powders are not created equally. We use Sherwin William’s most advanced ultra-durable primer and top coat.
  • Hardware. Our powder line is highly engineered and 2400’ long with plenty of breathing room for thorough processing. Trailers flow through at a steady pace with no pushing or pulling required. It includes a number of pits and platforms throughout to enable operators to access trailers, over and under, comfortably and with ease which results in excellent coverage and consistency.
  • Purity. We use an extensive system of filters, separators, and refrigerated and dessicant air dryers to ensure that the compressed air we use for powder application is extremely pure, dry, and uncontaminated.
  • Control. All powder is applied in an environmentally controlled room for optimal application consistency. 60-80 degrees F.
  • Ovens. They’re convection ovens with several thousand points of air flow, electronically monitored and balanced, and have 18 million BTU’s of natural gas powered heat available to ensure consistent, complete powder curing.
  • Process. We audit the entire process, a multi-point inspection, every single day of operation to ensure that every machine, step, and process is performing consistently and optimally. Additionally, critical performance factors are monitored hourly at each booth to maintain tight controls and standards.

Safer. Stronger. Longer.

Blackwood Lumber provides your Diamond C trailer a great alternative to traditional lumber floors. It not only looks great, but also features enhanced traction, safety, & durability.

What is Blackwood Lumber?

Blackwood Lumber is rubber infused, pressure treated pine flooring that provides enhanced traction in the wettest conditions, outstanding impact resistance in the toughest environments, and increased flooring lifespan from its no fade, no crack technology.

Features:

  1. Blackwood Lumber is made with the highest quality lumber, then infused with industrial-grade rubber. This provides increased protection allowing the Blackwood to withstand heavy impact that would crack and damage normal lumber.
  2. Blackwood also provides superior traction, which helps prevent slipping and allows safer and easier loading of equipment during wet conditions.
  3. Blackwood lasts longer than normal lumber because of the rubber infusion process. It won’t fade, crack, or stain, and can easily be cleaned with water.

We offer Blackwood Lumber in either full width or outer options:

*Note: If you are hauling primarily steel tracked equipment such as bulldozers or excavators, consider our hard OAK FLOORING as a good alternative to Blackwood Lumber

Trailer Flooring Guide Video

Watch below as Jacob goes in-depth on all our flooring choices, shows them up-close on our trailers, and gives tips on which one you should choose for your specific hauling needs.

Pressure treated Pine flooring is the most commonly used wood flooring material in trailers. The abundant supply of Pine wood in the south coupled with its sturdy nature make for a solid basic flooring choice.

When looking at Pine flooring in the trailer industry there are two different elements that you should consider:

  1. Is it treated? Treated means that the lumber has been run through a process where an anti-rotting solution is injected into the pores of the wood to lengthen the life of the wood out in nature’s elements. Some manufacturers still choose to use an untreated product to reduce cost. This does reduce cost in the short term but it also reduces the life of the floor of the trailer 10X and does not make for a good user experience long term. Diamond C ONLY uses pressure-treated lumber.
  2. Lumber quality is graded on a tiered system, the same system that the building construction industry uses; #1, #2 and #3 grades. #1 being the best and #3 being the “least good” of the three. Basically when you boil it down, the trailer industry primarily uses #2 & #3 grade. #2 vs #3 is going to have less knots, and the knots it does have will be smaller and tighter, have less edge wane (or uneven edges), and less tendency to crack. Similar to the the treated vs. untreated scenario, some manufacturers will opt for the lesser quality #3 grade lumber to save a few dollars in production, which ultimately costs you more in the long term in maintenance and replacement costs. Diamond C only uses #2 or better graded lumber for our trailer floors.

For an even more durable flooring option consider our OAK FLOORING upgrade, or for maximum loading traction check out BLACKWOOD LUMBER.

When you know the job is grueling and the floor of your trailer is going to take a beating, the Oak Floor option is for you. Since Oak is a hardwood, it is a much denser wood than industry standard Pine, therefore it is not as susceptible to being gouged, scraped, or broken down like its softer pine counterpart.

Oak is ideal for use with tracked equipment such as dozers, skid steers, excavators, etc. Additionally, Oak is a great choice for users that engage in a high amount of side loading various palletized material.

Oak flooring is most popularly found on our heavier duty flatbed trailers:

– Gooseneck: FMAX212, FMAX216
– Pintle Hitch: PX212, PX310, PX312, PX216
– Step Deck: SDX212, SDX216
