CORROSHIELD® Fasteners METAPP® Concealed Fixing Screw
METAPP® Concealed Roofing Fasteners are designed for concealed/secret-fix applications, where the cladding fastener is driven through a concealed clip into the supporting steel — helping deliver a cleaner finish while keeping fixing points protected under the profile. As trusted self drilling screws India manufacturers supply for modern construction, METAPP® concealed fixing screws combine precision engineering with long-term weather resistance.

Best-Fit Applications
METAPP® metal roofing crest fix fasteners are recommended for:
Concealed clip fixing systems — where concealed roofing fasteners ensure a clean, exposed-free finish
Concealed / secret-fix roof and wall cladding profiles requiring reliable stainless steel cladding screws
Steel purlin clip fastening using high-performance metal to metal fasteners
Where METAPP® is Used?
Use-case:
/1
Fixing concealed clip systems to steel purlins in secret-fix roofing applications — the core function of concealed roofing fasteners in PEB and industrial construction. These metal roofing crest fix fasteners ensure the clip stays firmly locked to the purlin without any visible fixing point on the roof surface.
/2
Modern roofing systems where weather resistance, hidden fastening, and long-term durability are critical — making stainless steel cladding screws the preferred choice for architects and contractors who demand both performance and aesthetics.
/3
Clip-through fastening applications where the screw is driven through a concealed clip into the supporting steel section — requiring metal to metal fasteners that deliver consistent torque and holding strength. For projects across India, these self drilling screws India suppliers offer are engineered to meet both structural and corrosion resistance demands.
Optional “Common sectors”:
PEB buildings, industrial sheds, warehouses, commercial complexes, logistics facilities, manufacturing units, and modern infrastructure structures — all sectors where cladding fasteners and concealed roofing fasteners play a critical role in weatherproofing and structural integrity.
