Astino Uni-Purlin & Metal Framing System
The Channel Styles and Combinations You NeedIntroduction
Featuring the Unique Uni-Purlin Connection
No Welding
No Drilling
100% Adjustable
100% Reusable


Hex-head bolt threads easily into a spring nut, connecting fitting to channel in quick one-hand operation.

Nut teeth create a vice like grip,
tying sides together in a strong “box” configuration, when the nut is tightened against the in turned channel edges.

Several channel sizes and hundreds of fittings give you engineered solutions to a virtually limitless variety of projects.

Spring allows precision placement anywhere along channel length then holds the nut in position while connection is completed.
Insert the spring nut anywhere along the continious slotted channel. Rounded nut ends permit easy insertion.

Materials & Finishes
Materials
Uni-Purlin
Uni-Purlin channels are steel from 1.6mm to 2.5mm, they are also available in Mild Steel, Pre-Galvanized. (G.I)
Mild Steel Channels
Mild Steel Channels are rolled using material formed by: JIS G3141 SPCC-SD equivalent to BS DIN EN 10130 and the minimum yield stress for our channel system is Ys=260N/mm2.
Pre-Galvanized Channels
Pre-Galvanized Channels are rolled using material formed by: JIS G3302 equivalent to BS EN 10326 and the minimum yield stress for our channel system is Ys=260N/mm2.
Uni-Purlin fitting Comply with BS1449Part1:1983 or BS4360:1927 and are manufactured from hot-rolled, picked and oiled steel plates, strip or coil. They have a minimum yield stress of 170N/mm2 as specified in BS6946:1988.
Comply All fittings are manufactured from 6mm thick material unless specified otherwise. Uni-Purlin fitting can also be obtained in stainless steel.
Uni-Purlin Channel Nuts are made from high quality steel bar.
Finishes
Hot-Dip Galvanized
Hot-dip galvanizing is a process where completely manufactured or roll-formed steel is chemically cleaned of all contaminants and then dipped in molten zinc. This will allow a coating consisting of iron/zinc-alloys which are usually over-coated with a layer of relatively pure zinc.
All hot-dip galvanizing is applied in accordance with ASTM A123:1989/BS EN ISO 1461:1999(E) which supersedes BS729:1971. The zinc coating thickness varies from 45μm (up to 2mm thick material for bolts and nuts) to 55μm (for at least 5mm thick material).
Pre-Galvanized (G.I)
Sheet metal (steel strip) is hot-dip galvanized in a continuous process which yields an even zinc coated sheet with a bright smooth metallic finish. Materials such as stell is galvanized prior to the manufacturing (roll-forming or press operations) of channels or fittings. All “pre-galvanized” steel used is in accordance with BS2989:1982 and usually grade Z275. Pre-Galvanized Hot Dipped Zinc Coated Steel JIS G3302.
Special Coating
Special Coating are also available upon request for all the channels and fittings: Epoxy Coated, Polyester Powder Coated and Thermoplastic Coated.
Plain (Mill Finish) Steel (Black)
Uni-Purlin channels and fittings are untreated and retain an oiled surface from the rolling or pressing process. Alternative steel grades and surface finishes are available upon request, but may be subject to minimum order quantities. Hot rolled steel P&O, JIS G3131 SPHC.

Technical Brief
Pre-Galvanized steel
Pre-Galvanized steel (JIS G3302 SGHC/SGCC or BS EN 10142)
Pre-Galvanized steel is produced by running the steel sheet though a bath of molten zinc in a continuous process. The thickness of the zinc coating is less than that of hot dip galvanized products. This zinc coating is also interrupted at edges where the material is cut or punched. Some zinc is pushed over the cut edges during the cutting process to offer some protection. Products made from pre-galvanized materials are suitable for indoor use.
Electro Galvanized Steel (EG)
Electro galvanized steel (JIS G3313 SECC)
This is process whereby the steel is passed continuously through a series of plating cells where zinc is deposited onto the steel surface through the electrolysis process. The protective zinc coat thus obtained is relatively thinner than the material obtained by hot dip galvanizing. The finished products are usually recommended for indoor application in dry areas.
Epoxy Powder Coated (EPC)
Powder coating is a process whereby the powdered resin and the steel product are electro are statically charged with opposing potential. The powder is sprayed onto the product and an even coat is formed. The coated product is then passed through an oven for baking to produce a glossy and hard finish. This coat can provide corrosion resistance against atmospheric moisture but not against more aggressive environment. It is recommended for indoor applications.
Powder coating can be applied to products with the following finish.
Mild steel mill finish
Hot dip galvanized finish
Pre-galvanized steel finish
Electro galvanized steel finish
Hot Dip Galvanized After Fabrication (HDG)
The most common selection for outdoor application is hot dip galvanized. After the cutting, bending and welding operation, the completed product goes through a series of treatment to remove grease and rust before being immersed completely into a bath of molten zinc. This complete immersion allows the zinc to bond onto every exposed surface of the product thereby affording exceptional protection, Defending on the environment, protection , Depending on the environment, protection can last for many years.
