Overview

What it is

Façade stone needs mechanical support, not just adhesive. Anchors, including stainless pins and dowels, kerf (slot) clips, undercut anchors and rail sub-frames, transfer each panel's weight and wind load to the structure while allowing for movement.

In ventilated façades, stainless steel or aluminium sub-frames carry the panels with an air gap behind. Anchor design is engineering work, based on the stone's tested strength at the anchor point.

Types
Dowels and pins, kerf clips, undercut anchors, rails
Materials
Stainless A2/A4 (304/316), aluminium sub-frames
Design
Dead load, wind load, seismic where required
Standards
EN 1469 (cladding), ASTM C1242 (attachment)

Applications

Best used for

  • Ventilated and rainscreen façadesPanels on sub-frames.
  • High-rise claddingEngineered for wind and movement.
  • Heavy interior claddingLobbies and atriums.
  • Soffits and overhead stoneWhere failure isn't an option.

Timing

Best time of year to buy

Consumables are bought all year, so timing is about stock: order ahead of the Lunar New Year shutdown in China and the August break in Italy, and buy trial quantities at the spring and autumn fairs.

Best time to buy Normal Slower or pricier
  • Chinese toolmakers close for Lunar New Year; place large orders by early December.
  • Italian and Spanish makers slow in August.
  • Hold four to eight weeks of stock of your fastest-moving tools to ride out shipping delays.

Import costs

Tariffs and import duties

Base duties for the main import markets, the extra US surcharge by origin, and the trade remedies to check before you quote a landed price.

HS codes

  • 7318Bolts, screws and anchors
  • 7326.90Other articles of steel
  • 7616Aluminium articles (rails)

Base import duty (MFN)

  • United StatesFree to 8.5% MFNPlus Section 232 metal tariffs on many steel and aluminium articles.
  • European Union2.7% to 3.7%
  • United Kingdom0% to 2%

Importing into the US? Add the 2026 origin surcharge

Section 301 rates in force since 24 July 2026, stacked on the MFN rate above.

  • Germany flagGermany10% min.Section 301 (2026) tops the duty up to at least 10% in total; no surcharge if MFN is already higher.
  • Italy flagItaly10% min.Section 301 (2026) tops the duty up to at least 10% in total; no surcharge if MFN is already higher.
  • China flagChina+12.5% & 30112.5% Section 301 (2026) plus the legacy China Section 301 duty (25% on most stone and machinery lines), on top of MFN.
  • US: steel and aluminium anchors and rails are likely to fall under Section 232 (up to 50% on metal articles). It is often the biggest duty on a façade package; check the current list.

Rates checked October 2026. Indicative rates for planning, not a customs ruling. Duties depend on the exact tariff line, origin, trade agreements and the rules in force on the day of entry. Confirm with a licensed customs broker before you price an order.

Before you order

Buying checklist

  1. 1Anchors must be engineered: ask for calculations from a façade engineer.
  2. 2Specify A4 (316) stainless near coasts and pools.
  3. 3Test anchor strength in the actual stone (EN 13364 or equivalent).
  4. 4Isolate dissimilar metals to prevent galvanic corrosion.
  5. 5Anchored façades typically use 30 mm or thicker stone; confirm with your engineer.

Price level: A small share of façade cost, but the part you can't compromise on.
