Corner Beads & Caps shape, protect, and finish drywall edges, delivering straight, crack‑resistant corners that stand up to daily wear. This category covers metal corner bead, vinyl corner bead, paper‑faced bead, bullnose profiles, archway and flexible beads, L‑trim, J‑bead, and protective corner caps for high‑traffic areas. Whether you are a pro taper or a first‑time DIYer, the right bead speeds up finishing and improves results.
Galvanized steel offers crisp lines and strong impact resistance for hallways and commercial sites. Vinyl and PVC resist corrosion in moisture‑prone spaces like bathrooms and basements, and cut cleanly with snips or a utility knife. Paper‑faced metal embeds quickly with joint compound, reducing blistering and sanding time. Corner caps snap on to shield fresh corners during moves or to dress exposed edges on garage and shop walls.
Quick tips for a flawless finish:
- Choose profile: standard 90‑degree, bullnose, or specialty returns for windows and niches.
- Fasten with staples, nails, screws, spray adhesive, or a clincher; follow manufacturer spacing.
- Bed with setting‑type compound for fast turnarounds, then top with lightweight mud; feather 10–12 inches.
- Lightly sand, prime, and spot‑fill to reveal and fix imperfections before paint.
Benefits include straighter lines, fewer call‑backs, reduced cracking, and better impact resistance. Using quality beads cuts labor, shortens sanding, and delivers a professional drywall finish.
Browse Building Supplies > Drywall > Corner Beads & Caps to compare lengths, angles, materials, and accessories like corner clinchers, rollers, and sanding tools. Find trade‑rated brands, bulk contractor packs, and DIY quantities, plus guidance for measuring, cutting, fastening, and finishing. Upgrade your drywall corners for cleaner, longer‑lasting results on remodels, new builds, basements, and repairs. Compare square, bullnose, and tear‑away options, check bead length for wall height, and choose corrosion‑resistant materials for coastal projects, humid interiors, and exterior soffits too.
