  1. Temperature Change: 120 degF (67 degC), ambient; 180 degF (100 degC), material surfaces.

2.3METALS, GENERAL

  1. Metal Surfaces, General: Provide materials with smooth surfaces, without seam marks, roller marks, rolled trade names, stains, discolorations, or blemishes.

Alloys and tempers in first six paragraphs below are typical for products listed when used in railings; revise to suit structural performance requirements of railing designs indicated and to establish minimum strength properties.

For round tube railings, usually retain first three paragraphs below if Contractor is required to design railings. For pipe railings, retain only second paragraph unless first paragraph is required for other extrusions. For square tube railings, retain only first paragraph. Primary difference between round tubing and pipe is in outside dimensions. Pipe sizes are normally indicated by use of nominal pipe size designator and weight class or schedule number; for tubing, OD and wall thickness are used. See "Pipe vs. Round Tube" Article in the Evaluations in Section055213 "Pipe and Tube Railings."
