Frequently Asked Engineering & Procurement Questions (FAQ)

• How is model ES-2003 installed on structural substrates?

  Installation & Mounting Protocol

  Model ES-2003 utilizes the following connection logic: Mitered Corner Socket Joint | Connects Square Handrails | Cubic Block Profile. It is engineered to anchor securely onto specified concrete slabs or timber decking using high-tensile fasteners.

• What glass thickness or tube diameters fit model ES-2003?

  Hardware Sizing & Fitment Matrix

  Model ES-2003 is engineered for glass panels measuring and supports tube profiles 38.1, 42.4, 50.8 . Internal EPDM rubber gaskets cushion the fitment.

• What is the MOQ and lead time for bulk orders of ES-2003?

  Production Schedules & Lead Times

  Stock satin and mirror polished items ship within 15 days for 100+ pcs. Custom PVD finishes require 25 days. Priority scheduling applies for FCL container orders.

• How do I select between Grade 304 and Grade 316 for this accessory?

  Alloy Grade Selection Protocol

  Grade 304 is suited for dry indoor staircases. Marine Grade 316 contains Molybdenum, making it mandatory for outdoor decks, coastal salt spray, and swimming pool fencing.

• Can I obtain official Mill Test Reports (MTR) and BIM 3D STEP models for ES-2003?
