Body Armor Orders: 5–10 Day Lead Time Before Shipping

Spartan Armor Systems AR550 Level 3+ Steel Body Armor Plates are built for customers who want the proven durability and long service life that steel plates are known for, while also demanding better comfort and wearability than older single curve designs. These plates feature ATC, Advanced Triple Curve, which helps the plate conform to the natural shape of the chest and torso. The result is a more stable, body-hugging feel in the carrier, reduced pressure points, and improved comfort during long hours of training, range time, work, or preparedness use.

A key advantage of these plates is the Encapsaloc full coat spall mitigation. Steel armor can produce fragmentation, often called spall, when impacted. Encapsaloc is designed as a full coverage coating to help capture and reduce that fragmentation, improving the overall wear experience when the plate is used as intended and worn correctly in a compatible carrier. While no coating can eliminate all risk in every scenario, a quality full coat spall mitigation layer is an important feature for customers choosing steel armor as part of their protection setup.

These plates are marketed as Level 3+, which is a common industry term used to indicate performance beyond standard Level III. Note that “Level III+” is not an official NIJ protection level designation, and ratings can vary by manufacturer and test method. If you are comparing armor options, it is smart to evaluate what threats you are planning around, how you intend to use the plate, and whether steel, ceramic, or polyethylene is the right match for your mission and comfort priorities.

Why choose these plates

• AR550 steel construction for long term durability and confidence in hard use environments

• ATC, Advanced Triple Curve for noticeably improved comfort and fit

• Encapsaloc full coat spall mitigation to help manage fragmentation

• Two sizes available, 10×12 for standard coverage, 11×14 for expanded coverage

• Great for training and preparedness where ruggedness and value matter

Size Options

10×12, Shooters Cut
A popular “standard” plate size used by many carriers and setups. This size balances protection area and mobility, making it a common choice for customers who want broad compatibility and a lighter, more streamlined profile.

11×14, Shooters Cut
Expanded coverage for larger frames or for anyone prioritizing maximum torso coverage. This size can be the right move if you have a bigger chest measurement, want more vertical coverage, or simply prefer a larger protective footprint.

Fitment and Carrier Notes

Spartan Armor Systems AR550 Level 3+ Steel Body Armor Plates are intended for plate carriers sized to match the plate dimensions. Before ordering, confirm your carrier plate pocket size and measure your torso to choose the right coverage. Many customers prefer 10×12 for daily training and mobility, while 11×14 is often chosen for broader coverage and larger builds.

Comfort and Wearability

The Advanced Triple Curve profile is the standout feature for comfort. Flat or single curve plates can feel like a rigid board against the chest, especially when you sit, kneel, or move dynamically. Triple curve geometry helps distribute contact across the torso more naturally, which can reduce hotspots and improve stability in the carrier. If you have worn older steel plates before and disliked the fit, the ATC profile can be a meaningful upgrade.

Important Use Notes

Body armor is a serious product and should be selected carefully. Always wear plates in a properly fitted carrier, follow all manufacturer guidance, and understand that armor performance can depend on hit location, distance, ammunition type, velocity, and real-world variables. Steel armor can be an excellent choice for certain users, especially when ruggedness and long term durability are priorities, but it is not the best fit for every use case.

Spartan Armor Systems AR550 Level 3+ Steel Body Armor Plates are a strong option for customers who want steel durability, improved comfort from a triple curve design, and the added benefit of a full coat spall mitigation layer. Choose 10×12 for standard fitment and mobility, or step up to 11×14 for expanded coverage.
