Ultratape Professional Flexible Metal Corner Tape 50mm x 30m | Heavy Duty Galvanised Steel for Internal & External Plasterboard Corner Reinforcement

Ultratape Professional Flexible Metal Corner Tape 50mm x 30m

Drywall finishing often fails at the corners due to structural movement or poor bead adhesion on non-standard angles.

This flexible metal tape solves the headache of cracked joints by providing a steel-reinforced bond that moves with the building.

The Engineering of Flexible Reinforcement

This product combines the tensile strength of steel with the porous adhesion properties of high-grade paper tape.

The result is a composite material that manages shear forces better than traditional plastic or metal beads.

Galvanised Steel Bonding

The two metal strips are precision-bonded to the paper backing to ensure they cannot delaminate under stress.

This bond is designed to withstand the alkaline environment of jointing compounds without failing.

Corrosion Resistance Tech

The steel undergoes a hot-dip galvanisation process to prevent oxidation during the drying phase of the plaster.

This protection is vital for long-term finish quality in bathrooms and kitchens.

Paper Adhesion Surface

The paper used is treated to allow jointing compound to penetrate the fibres for a mechanical lock.

This prevents the "peeling" effect often seen with lower quality tape products.

UK Climate and Environmental Performance

The UK construction industry must account for high humidity levels which can soften traditional paper-only tapes.

The steel core in this tape provides a rigid skeleton that maintains its shape even when the paper is damp.

Cold Weather Durability

Standard plastic beads can become brittle and crack during harsh British winters on unheated sites.

Galvanised steel remains ductile and maintains its structural integrity at sub-zero temperatures.

UV and Thermal Stability

Temperature fluctuations in modern glass-heavy extensions can cause significant expansion and contraction.

The thermal expansion coefficient of this tape is compatible with standard British plasterboard and scrim.

Industrial Application and Sector Focus

Residential Construction

This tape is the industry standard for new build housing where rapid settlement often causes corner cracks.

It allows contractors to finish rooms faster without waiting for traditional bead adhesive to cure.

Signage and Display

Exhibition stand builders use this tape to create sharp, professional edges on temporary structures.

The flexible nature allows for complex geometric shapes that rigid beads cannot accommodate.

Commercial Fit Outs

In high-traffic office environments, the steel reinforcement protects corners from trolley impacts and heavy use.

It offers a higher level of protection than standard jointing tapes alone.

Problem Solution Scenarios

Scenario 1 - Out of Square Loft Conversion

Timber frame loft conversions often have rafters that meet at non-90 degree angles.

This tape flexes to any angle, ensuring a perfect finish on even the most awkward junctions.

Scenario 2 - High Traffic Hospital Corridors

External corners in healthcare facilities are prone to damage from beds and trolleys.

The twin steel strips provide a rigid barrier that absorbs impact and prevents plaster chipping.

Scenario 3 - Moisture Heavy Kitchen Renovations

Humidity around cooking areas causes standard paper tape to bubble or lose its bond.

The galvanised steel maintains the corner shape while the high-bond paper resists steam penetration.

Surface Preparation Masterclass

Quality finishes depend on the substrate preparation before any tape is applied to the wall.

Follow these trade steps to ensure your flexible steel tape never fails.

Dust and Debris Removal

Wipe down all plasterboard edges with a damp cloth to remove fine drywall dust.

Dust is the primary cause of adhesion failure as it prevents the compound from grabbing.

Degreasing Metal Substrates

If applying over existing metal structures, use a professional degreaser to remove oils.

Contaminants on the surface will create a barrier that stops the jointing compound from setting correctly.

Installation Guide

1. Measure the corner height and cut the tape 10mm shorter than the total length to allow for floor clearance.
2. Apply a generous 3mm layer of jointing compound to both sides of the corner using a 4-inch taping knife.
3. Fold the tape along the centre crease and press it firmly into the wet compound with your fingers.
4. Use the taping knife to bed the tape into the compound, starting from the centre and working outwards.
5. Apply 25kg of pressure to the knife to squeeze out excess compound and ensure the steel strips are flush.
6. Wipe away any surplus material from the edges immediately to minimize sanding later.
7. Allow the first coat to cure for at least 12 hours depending on site temperature and humidity.
8. Apply a second, wider coat of compound to feather the edges out by 150mm on each side.
9. Sand the dried surface with 120-grit abrasive until the transition between tape and board is seamless.
10. Check for any high spots or exposed steel before applying your final paint or decorative finish.

Frequently Asked Questions

Can I use this tape for external render applications?

No, this product is designed for internal plasterboard and dry-lining rather than wet external rendering.

Is it better than using a traditional metal corner bead?

It is more versatile for non-90 degree angles and significantly easier to transport to sites.

Does it require a specific type of jointing compound?

It works with all standard British drywall compounds, including all-purpose and lightweight varieties.

Can I use this on curved walls?

While it flexes for angles, it is not designed for radius curves; use a specialist flexi-bead for that.

Will the steel strips rust over time?

The hot-dip galvanised coating prevents rust even in humid rooms like bathrooms.

How do I cut the tape to length?

Standard tin snips or heavy-duty scissors are required to cut through the steel reinforcement.

What happens if I don't use enough compound?

Insufficient compound will lead to air pockets and eventual delamination of the tape.

Is the dispensing box necessary?

The box keeps the roll tidy and prevents the steel strips from unravelling or getting kinked.

Can I paint directly onto the tape?

No, the tape must be fully embedded and feathered out with compound before painting.

Does it work for ceiling to wall junctions?

Yes, it is ideal for internal ceiling corners, especially in timber-framed properties.
