CORROSHIELD® Fasteners METAPP® Valley Fixing Screw
METAPP® Valley Fixing Screws are premium valley fixing screws designed to attach the sheet to the roof/wall frame. As trusted metal roofing screws for steel purlins and sheet metal to steel screws, they should be fixed perpendicular to the sheeting/cladding for best water-tightness. The catalogue notes that valley fixing on roof is not recommended in high rain zones — making correct specification of roofing sheet fixing screws and self drilling screws for metal roofing essential for long-term performance.
Available with hex washer head roofing screws configuration and EPDM washer roofing screws options, METAPP® serves as a complete solution for metal to metal fasteners, steel to steel fasteners, and cladding fasteners — trusted by PEB roofing fasteners India contractors and wall cladding screws supplier India networks.

Where METAPP® Valley Fixed Screw is Used?
Use-case:
/1
Fastening metal roofing and wall cladding sheets directly to steel purlins with secure clamping action — the primary role of metal roofing screws for steel purlins and roofing sheet fixing screws.
/2
Valley fixing applications where firm sheet-to-structure contact and load distribution are essential — requiring reliable valley fixing screws and metal to metal fasteners.
/3
General-purpose metal-to-steel connections requiring consistent torque transfer and head stability during installation — ideal for metal to metal self drilling screws and steel to steel fasteners.
/4
Installations exposed to weather where a bonded sealing washer helps prevent water penetration — a key feature of EPDM washer roofing screws and self drilling screws for metal roofing.
/5
High-vibration environments where integrated washer support improves pull-through resistance and joint durability — important for cladding fasteners, PEB roofing fasteners India, and wall cladding screws supplier India projects.
Optional “Common sectors”:
Pre-engineered buildings (PEB), industrial sheds, warehouses, logistics centers, commercial roofing projects, agricultural buildings, and infrastructure structures.

How to Select the Right METAPP® Valley Fixing Screw?
Confirm the roofing profile – Select the screw suitable for valley fixing to ensure proper seating and load transfer — choosing the right valley fixing screw and roofing sheet fixing screws for the profile type.
Check purlin thickness – Match the drill point capacity and length with the steel support gauge — critical for metal roofing screws for steel purlins and self drilling screws for metal roofing performance.
Ensure sealing performance – Use EPDM washers to prevent water ingress and maintain weather tightness — the standard for EPDM washer roofing screws and metal to metal fasteners in exposed environments.
Consider exposure conditions – Choose appropriate corrosion protection for coastal or industrial environments — essential for cladding fixing screws India, PEB roofing fasteners India, and metal roofing crest fix fasteners in harsh conditions.
Installation guidance
Install perpendicular to the sheet/cladding.
For cladding, fix in the middle of the rib.
Tighten until washer seals; do not overdrive.
