The Calder Lead Striking Plate (30cm x 35cm x 2mm) is a heavy-duty stainless steel accessory engineered to support, shape, and dress lead sheet during roofing and construction work. This specialist tool helps roofers achieve clean, professional details without damaging the soft metal.
Key Specifications and Design
Dimensions: 350mm x 300mm x 2mm (30cm x 35cm)
Material: Durable, high-grade stainless steel
Design Features: Built with precision cut-out sections tailored for handling tight or awkward angles
Build Quality: Rigid, impact-resistant surface that withstands repeated hammer strikes and tool contact
What Does It Do?
When working with rolled lead sheet, getting sharp folds and neat finishes requires a solid backing surface that absorbs and distributes force evenly. The Calder striking plate serves several critical functions on site:
Supporting Lead Bossing: Provides a firm base beneath the lead sheet while you stretch, shape, and contour the metal.
Dressing Roll Ends: The integrated cut sections make it easy to tuck, shape, and finish lead roll ends cleanly.
Working Corners and Complex Details: Offers rigid underside support in tight, awkward areas where free-hand shaping might tear or misalign the sheet.
Protecting Tools and Surfaces: Reduces bounce-back and guards against uneven deformation, cutting down on physical fatigue and material waste.
Why Choose Stainless Steel for Leadwork?
Lead is a soft, malleable material that demands respect during installation. Using makeshift backing blocks or hitting lead over unyielding or rough surfaces can score, thin, or puncture the sheet—violating British Standards or leading to premature leaks.
Stainless steel strikes the right balance: it is hard enough not to warp under a bossing mallet, yet smooth enough to let the lead glide and form cleanly across its surface.
Who Is It For?
Professional Roofers: Essential kit for traditional leadwork, dormer cheeks, gutter linings, and chimney flashings.
General Builders & Specialists: Useful for soft metal fabrication, architectural restoration, and detailed weatherings.
