Retail environments are tough, and you need displays that can handle heavy traffic without failing. You might be worried about your products falling over or looking cheap due to poor material choices.
The most common materials for endcap displays are corrugated cardboard, metal, wood, and rigid plastics. Corrugated fiberboard is the industry standard for temporary retail promotions because it is cost-effective, lightweight, and highly printable. Permanent fixtures often use steel or acrylic to withstand long-term wear in high-traffic store aisles.

Choosing the right material is not just about price; it is about structural integrity and how long you need the display to last. Let us look at the specific materials involved in different types of end caps.
What materials are pipe end caps made of?
Many people confuse retail terminology with industrial terms, so it is important to clarify this distinction. You need to know exactly what you are buying to avoid costly ordering mistakes.
Pipe end caps are primarily manufactured from industrial metals like carbon steel, stainless steel, or brass, as well as thermoplastics such as PVC and CPVC. These materials are designed to seal the end of a pipe to stop flow or protect threads. The choice depends strictly on pressure ratings and chemical compatibility.

Material Specifications and Industrial Application
When we discuss pipe end caps, we are looking at a completely different set of engineering requirements compared to retail displays. However, understanding these materials helps you understand structural limits. Pipe end caps are critical in construction and plumbing. They must withstand internal pressure and external environmental factors. The most common material is Polyvinyl Chloride (PVC)1. PVC caps are used in low-pressure settings, like residential drain lines. They are lightweight and resist corrosion but cannot handle high heat.
For high-pressure or industrial environments, metal is the only option. Carbon steel caps2 are used in oil and gas lines because they have immense tensile strength. Stainless steel is used where hygiene or corrosion resistance is key, such as in food processing plants. Copper caps are specific to water lines and HVAC systems because they conduct heat well and are easy to solder. Although my factory focuses on cardboard, understanding the difference between "holding water" and "holding weight" is vital. In the display world, we sometimes use rigid PVC tubes to reinforce cardboard structures, borrowing this concept of durability from the construction sector to ensure your displays do not collapse under heavy products.
| Material Type | Common Application | Key Feature | Pressure Resistance |
|---|---|---|---|
| PVC (Plastic) | Residential Drainage | Corrosion Proof3 | Low to Medium |
| Carbon Steel | Oil & Gas Pipelines | High Tensile Strength4 | Very High |
| Copper | Water Supply / HVAC | Thermal Conductivity | Medium |
| Stainless Steel | Food/Chemical Plants | Hygiene & Rust Proof | High |
I know that material failure is a major pain point for you. We apply this same rigorous mindset to our cardboard displays. I ensure my team tests every batch of raw material for strength, just like an engineer rates a pipe, so you never have to worry about a display collapsing in a store.
What are end cap displays?
You want your product to be the first thing a customer sees when they turn a corner. If you are stuck inside the aisle, you are fighting for attention, but the end of the aisle is prime territory.
End cap displays are retail shelving units positioned at the end of store aisles to maximize product visibility and traffic exposure. They are considered prime real estate in retail, designed to drive impulse purchases, highlight seasonal items, or launch new products. They can be temporary cardboard structures or permanent metal fixtures.

The Strategy of Prime Retail Real Estate
The structural anatomy of an end cap display is defined by its location and its purpose. In the retail industry, we call this "secondary placement5." The primary placement is the home shelf where your product usually sits. The end cap is the disruption point. It forces the shopper to stop and look before they turn into an aisle. Because these displays sit in high-traffic zones, they face unique physical challenges. They are bumped by shopping carts, kicked by passing customers, and restocked frequently by busy store staff.
This means the materials used for end cap displays6 must be more robust than standard shelf packaging. A typical cardboard end cap is not just a box; it is an engineered structure. We often use a "kit" format. This includes a base, a tray, and a header. For heavy items, like the hunting gear or crossbows you might sell, standard cardboard is not enough. We have to reinforce these end caps with internal dividers or support bars (sometimes made of metal or rolled paper) to prevent sagging. Retailers like Costco or Walmart have strict guidelines on dimensions and weight limits. If your end cap overhangs into the aisle by even an inch, it can be rejected. You need a design that fits the strict footprint while acting as a billboard for your brand.
| Feature | Standard Shelf | End Cap Display7 |
|---|---|---|
| Visibility | Low (Blends in) | High (3 sides visible) |
| Traffic Flow8 | Destination only | High intercept traffic |
| Durability Need | Medium | High (Cart collisions) |
| Stock Turn | Standard rate | Fast / High volume |
I have seen too many brands lose money because their displays arrived damaged or sagged after two days. I run my factory with a focus on structural integrity. We simulate store abuse during our prototyping phase to ensure your end cap stands tall and sells your product until the very last unit is gone.
What are display materials?
The difference between a display that sells and one that gets thrown away often comes down to the paper and glue. You need to understand the raw materials to control your costs and quality.
Display materials encompass the substrates used to build retail structures, including corrugated board, foam core, acrylic, and wood. Corrugated cardboard is the dominant material for temporary displays due to its strength-to-weight ratio and recyclability. Permanent displays often utilize steel, glass, or heavy-duty plastics to ensure years of usability.

Corrugated Board Grades and Printing Surfaces
When we talk about cardboard displays, we are not talking about standard shipping boxes. We are talking about high-grade corrugated fiberboard. This material consists of a fluted sheet sandwiched between two liners. The "flute" is the wavy part in the middle, and it determines the strength. For high-quality printing, we typically laminate a sheet of CCNB (Clay Coated News Back)9 onto the corrugated board. This gives a smooth, white surface that allows for lithographic or high-quality digital printing. This is crucial for your brand image. If the surface is rough, your logo looks washed out.
There are different flute sizes we use depending on the weight of your product.
• E-flute: Thin and good for small counter displays.
• B-flute10: The most common all-rounder, offering good crush resistance and a good print surface.
• BC-flute: A double-wall structure (two layers of flutes) used for heavy items, like pallet displays or heavy outdoor gear.
For your specific needs with heavier hunting products, a single layer of B-flute might be too weak. We would likely recommend a reinforced B-flute or a double-wall structure to ensure the display does not buckle under the weight of a crossbow or heavy tools. The paper weight also matters. We use varying weights measured in grams per square meter (GSM). Higher GSM means a stiffer, stronger display, but also a higher cost.
| Flute Profile | Thickness (Approx) | Best Use Case | Print Quality Potential |
|---|---|---|---|
| E-Flute11 | 1.6mm | Small Counter Units | Excellent |
| B-Flute12 | 3.2mm | Standard Floor Displays | Very Good |
| C-Flute | 4.0mm | Shipping/Stocking Boxes | Good |
| BC-Flute | 6.4mm | Heavy Duty / Pallets | Good (needs thick liner) |
I use my years of experience to select the exact material mix that balances your budget with the necessary strength. I will send you a white sample first so you can physically feel the material strength before we ever print a single sheet, ensuring no nasty surprises in mass production.
What are end caps in construction?
Construction terms often overlap with retail terms, and this can cause confusion during procurement. You might be searching for structural components and end up with display results, or vice versa.
In construction, end caps refer to protective covers installed on the exposed ends of planks, roofing profiles, or structural beams. They are typically made from aluminum, galvanized steel, or durable vinyl. Their primary function is to seal the material against moisture ingress, prevent pest entry, and provide a finished aesthetic look.

Weatherproofing and Structural Protection
While this blog focuses on retail, the engineering principle behind construction end caps is relevant: protection of the core. In construction, an end cap is a barrier. If you leave the end of a composite deck board or a roofing ridge open, water gets inside. This leads to swelling, rot, or rust. The materials used here must be UV stable and non-corrosive. Aluminum is popular for roofing because it does not rust. Vinyl is used for decking because it can be molded to match the wood grain and color.
Interestingly, this concept applies to your retail displays too. The "raw edges" of a cardboard display are its weak points. Moisture from floor cleaning machines in supermarkets can wick up through the bottom of a cardboard display, causing it to collapse. This is why we often add a "waterproof tray13" or a plastic clip called a "mop guard14" to the bottom of our floor displays. It acts just like a construction end cap. It seals the vulnerable cardboard base from water damage on the store floor. Just as a builder protects the beam, we must protect the display base. Without this consideration, a display placed near the produce section or a snowy store entrance will fail in days.
| Function | Construction End Cap | Retail Display Base Protection |
|---|---|---|
| Primary Threat | Rain / UV Light | Mops / Floor Moisture |
| Material Used | Aluminum / Vinyl | PP Tape / Plastic Tray |
| Goal | Prevent Rot/Rust15 | Prevent Structural Collapse16 |
| Lifespan | 20+ Years | 4-8 Weeks |
I take the "construction" of your displays seriously. We can add waterproof bases or clear plastic feet to your cardboard stands. I offer these small upgrades because I know they make the difference between a display that lasts the full promotion and one that gets thrown out early.
