Standard 40Nb	MD504 (Straight) MD598 (Rolled) MD599 (Custom Bend)	Most jobs	40Nb pipe is the standard pipe used on products at Moddex. 40Nb pipe is steel/grade C250 that has a protective coating of G390 Hot-dip Galvanized.
Powdercoated ZP & PC	MDxxxPC P & F (ZP & PC) PO (ZP & PC)	Powdercoat can be applied to jobs on customer request	ZP & PC is used on black pipe. The pipe is sprayed with Zinc Prime (ZP) and then powdercoated (PC). P & F stands for Pipes and Fittings PO stands for Pipes Only
Powdercoated HDG & PC	MDxxxPC P & F (HDG & PC) PO (HDG & PC)	Powdercoat can be applied to jobs on customer request	HDG & PC is used on pipe that has been or will be hot-dipped galvanized (HDG), and then gets powdercoated (PC). P & F stands for Pipes and Fittings PO stands for Pipes Only
Green	N/A	Used for when creating bent pipe that has a tail less than 170mm or a front less than 50mm	Green essentially means additional pipe length which is used on pipes that won’t be able to be bent in the bender. Green is also used on rolled pipes to allow the machines to roll the pipe.
Black	MD504B (Straight) MD598B (Rolled) MD599B (Custom Bend)	All fabricated products	Black is applied to any pipe that is going to be fabricated. This pipe has not yet been galvanized. Black pipe is steel/grade C350.
Rolled	MD698-10 (Stainless Steel) MD598 (HDG) MD498.T4 (Aluminium)	Used typically on any curved surface Examples includes footpaths, skateparks, and silos	Rolled pipe/tube is outsourced and not rolled by Moddex. Because of this, rolled pipe/tube has its own booklet that is sent to the company that’s outsourced. Rolled pipe/tube has an additional 300mm of green on both ends, this is so that it can be rolled. With double span TR we can use a MD201.48 as a top fitting to allow the rolled pipe to run through, as long as the rolled pipe doesn’t have a dramatic radius.
Aluminium	MD404.T6 (Straight/Stanchion) MD498.T4 (Rolled) MD499.T4 (Custom Bend)	Aluminium can be applied to jobs on customer request	Aluminium pipe comes in 2 different aging processes, T6 which is used just as straight pipe, and T4 which is used for rolling and bending. Jobs using aluminium pipe will need to also use aluminium 300 series fittings.
Stainless Steel	TUFFRAIL MD604 (Straight) MD698 (Rolled) MD699 (Custom bend) Other 50.8.TUBE.LENGTH (Straight) 50.8.ROLLED.LENGTH (Rolled) 50.8.BEND.LENGTH (Custom Bend)	Stainless Steel can be applied to jobs on customer request	When used with TUFFRAIL, stainless steel pipe is used at a diameter of 48.3mm With this size pipe, Moddex 600 series fittings are used. When used with ASSISTRAIL, stainless steel tube is used at a diameter of 50.8mm x 1.6mm Stainless Steel tube will need to use custom fittings (Hammersmith) as Moddex does not supply standard parts for this type of tube.
Heavy Duty	MD504HD MD504.6500HD MD504B.6500HD	Stanchions that are supporting CB panels with an overall height equal to or larger than 1500mm	Heavy Duty pipes are only used as stanchions and can fit standard Moddex 100 & 200 series fittings.

They have their own pipe fittings that are standard Moddex parts. In schools we only use 32Nb on double rail systems, this includes; AR110, AR120, AR130, AR140, AR160, CB50, and CB55.
Extra Light	MD504.6500XL	Used for extending MD201.48 and MD748.42 as a combo	Extra light pipe is used in-between a MD201.48 and MD748.42 to extend the swivel railing bracket out when required.
