Most drywall corner beads are available in various materials, including metal and vinyl. Some corner beads are "paper-faced," but even their core components are usually made of metal or vinyl.
The traditional corner bead material, metal, has been used to finish outside corners for generations. They can be installed with screws or nails and are relatively durable. But while metal corner bead has been used for a long time, that doesn't necessarily make it the best option.
The outside corners of your walls are extremely susceptible to damage because they are often kicked, struck or smashed, caused by anything from children playing to moving furniture. Metal corner beads will not shatter or break from this abuse, but they often dent. Once dented, the only way to repair a corner bead is to replace it, which is a time-consuming situation.
Additionally, metal corner beads are prone to rust and corrosion in damp locations such as bathrooms and basements, which can create longevity issues.
To make matters worse, metal corner beads are susceptible to denting, bending and damage before even reaching the jobsite — this can happen as easily as being jostled too much in the back of the truck on the way to work — wasting precious resources.
While metal is the traditional material used for corner beads, vinyl is the contemporary preference for modern drywall contractors and DIY enthusiasts.
Modern vinyl types of drywall corner beads provide significant advantages over their traditional metal counterparts, including, most importantly, durability.
Vinyl is virtually immune to denting and offers superior durability to metal types of drywall corner beads. This superb dent resistance results in a longer-lasting outside corner that maintains its visual and structural integrity far longer than its metal counterparts.
In addition to its dent resistance, vinyl’s flexibility allows it to combat damage or deformation from transportation. Plus, it maintains a consistent, straight edge during installation and finishing.
Vinyl is suitable for any wet, humid environment as it will not rust or corrode. Vinyl's natural flexibility allows it to absorb movement without creating the unsightly cracks that metal corner beads can create. This flexibility creates the ability to efficiently finish curves and other contours that are difficult for metal corner beads.
Paper-faced types of drywall corner beads are another modern solution to many of the problems produced by metal corner beads.
Paper-faced corner beads are installed similarly to how you tape your inside corners.
Lay a bed of all-purpose joint compound on either side of the outside corner.
Place a paper-faced corner bead on the outside corner of the bed of the joint compound.
Run a taping knife along either side of the corner bead to seat it firmly and remove any excess compound.
The paper-faced drywall corner bead was developed to eliminate the cracking and nail popping common in metal corner bead installations. Unfortunately, if not installed correctly, paper-faced corner beads can peel away from the wall, which results in an unsightly and unacceptable wall finish. Peeling can be difficult to remedy and often requires removal and re-installation.
In addition to the variety of materials used to make them, there are numerous drywall corner bead types, each with different profiles, purposes and functions.
A soft profile corner bead is one of the most common styles for residential and commercial settings. A slightly rounded corner profile provides a smooth visual appearance while still providing a gentle radius.
This sharply profiled corner bead provides precisely the aesthetic that its name implies. By creating a sharp outside corner, you can use less mud and no setback to finish it — saving you time and material.

Drywall corner beads are products that are used to finish an outside corner where two pieces of drywall meet. While the surface of a sheet of drywall is durable, its edges are brittle and easily damaged, necessitating corner beads as added layers of protection. Corner beads come in various sizes, typically 8-12 feet long, so you can cut them to length on-site.
Corner beads create a straight, consistent and durable profile that is easy to finish and looks great.
Corner beads are typically made of metal, vinyl or are "paper-faced," meaning they combine metal or vinyl and paper. Each material has its own unique strengths and weaknesses, but one type, in particular, is definitively the best corner bead for drywall.
The most common and traditional type of corner bead, metal corner beads, have been installed by drywall professionals and avid DIYers alike for generations.
Although contractors have used metal for outside corners longer than other materials, there are several reasons why it is not the best corner bead for drywall.

The outside corners are the most likely areas of your walls to sustain damage. Whether from people, animals or furniture, your outside corners will likely take a beating.
Although metal corner beads will not shatter, they will undoubtedly dent upon significant impact. Unfortunately, you cannot repair a dented corner bead, and you will likely need to replace it.
Metal corner beads can be prone to rusting in damp applications such as bathrooms and basements.
In transport, metal corner beads are often dented, bent and damaged, which makes them difficult, if not downright impossible, to use.
Metal corner beads can be the culprit of significant nail popping or cracking in a finished wall.
The drywall industry developed paper-faced corner beads to help prevent the irritating cracking and nail popping common with its metal counterpart.
The solution to this problem is to install a paper-faced corner bead by "mudding it in," a process by which the corner bead is held in place by a bed of joint compound. Paper-faced corner beads are available in both metal and vinyl—which means that all paper-faced corner beads are not created equally.
While paper-faced metal beads eliminate cracking and nail popping, they create new and different problems.
If installed incorrectly, a paper-faced corner bead can separate or peel away from the wall, which can compromise your corner and create an unsightly finish. To counteract the problem of peeling, a paper-faced vinyl bead like Fast Edge Paper features Mud Locks that grip into the mud.
Using vinyl to make corner beads creates a durable product that is immune to rust, dent-resistant and will not peel away from your wall.
Vinyl's superior flexibility allows it to quickly create curves and contours that would be painstakingly difficult to replicate with metal. In addition, vinyl is available in a much more comprehensive range of shapes and profiles than its metal counterparts, and it's easy to see why vinyl is the best corner bead for drywall.
Vinyl corner beads provide numerous advantages over metal and paper-faced alternatives, including resilience, elasticity, flexibility, the plentiful variety of product options, and the material's sustainability.
Whether during delivery from the manufacturer to the store or in the bed of your truck surrounded by tools and lumber, there is a good chance that your corner bead will be compromised somewhere along the line.
Metal corner bead bends, dents and bows will leave you with a product that is not straight and is challenging to install. On the other hand, vinyl is immune to such transportation-related disasters and will always bounce back to its original shape.
One of the biggest reasons vinyl is the best corner bead for drywall is its elasticity.
Whether you're moving furniture, carrying groceries or moving a bulky item like a stroller around the house, the outside corners of your walls are going to take a beating. Metal corner beads can dent irreversibly on impact. Vinyl corner beads, on the other hand, take the hit and bounce right back which prevents annoying and costly repairs.
The ability to curve is one of the many characteristics that sets vinyl apart from other types of corner beads.
Although you can use metal corner beads to finish curves using relief cuts and bending, creating the required smooth, consistent radius can be tedious and challenging.
Unlike metal, vinyl corner beads have no problem bending and curving to whatever contour your project requires.
The sheer number of product options available in vinyl compared to metal is another reason vinyl is the best corner bead for drywall.
Vinyl is available in multiple sizes of soft, sharp, bullnose and chamfered profiles, as well as reveal beads, shadow beads, J beads, L beads and much more.
Vinyl isn't just the best corner bead for drywall — when produced using sustainable practices, it can be the best corner bead for the planet.
Vinyl corner beads made by Trim-Tex are predominantly made from recycled materials, which keeps millions of pounds of plastics out of our landfills each year.
