Ordering Information5.1 When ordering or specifying welded wire mesh fencesystems for security applications, the appropriate mesh type,mesh description, fence height, post
16、size, post spacing, allow-able mesh-to-framework attachment methods, and finishshould all be defined to ensure that welded wire mesh panelsand all associated system components will be compatible in thetotal system installation.6. Materials and Manufacture6.1 Welded Wire Mesh Panels6.1.1 Finish6.1.1.
17、1 If Type 2 galvanized mesh is selected, the panelsshall be completely and uniformly zinc-coated by the hot-dipprocess in accordance with Specification F2453 after welding,shall be free from excessive accumulations of zinc in theapexes of mesh openings, and free from bare spots.6.1.1.2 If Type 4 col
18、or coated mesh is required, specify typeof coating, color, and thickness of finish in accordance withSpecification F2453. Specification F934 is noted for colorselection, though color coating shall not be limited to the listedcolors.6.2 Framework6.2.1 Line Posts: Fences designed to provide increaseds
19、ecurity levels are generally of greater heights, utilize smallermesh sizes and heavier gauges, and these factors result inadded wind load resistance. Line post selection and the spacingof the posts should be designed to meet the anticipated windloads based on the site geographical location and weath
20、erconditions. Increased post sizes or specific post spacing may berequired to compensate for wind loading or increased security.Determine the wind load requirements for a minimum 105 mphup to 170 mph wind according to ASCE/SEI 7-10 or consultthe fence system manufacturer. After calculating the posts
21、pacing and post dimension, select the post specification andprotective coating from Specification F1043, Heavy IndustrialFence Framework; Group IA Round Steel Pipe (SpecificationF1083 Schedule 40), Group IC Round Steel Pipe (ElectricResistance Welded Pipe), Group II Roll-Formed Steel Shapes(C-Sectio
22、ns), Group IV Alternate Design.6.2.2 Terminal Posts: End, corner, or pull posts are to be inaccordance with Specification F1043, Heavy Industrial FenceFramework; Group IA (Specification F1083 schedule 40 pipe),Group IC Electric Resistance Welded Pipe). Select the terminalpost size based on the line
23、post size.6.2.3 Rails: Top, intermediate and terminal post brace railswhen specified shall be in accordance with SpecificationF1043, Heavy Industrial Fence Framework; Group IA, (F1083schedule 40 pipe) Group IC (Electric resistance welded pipe)or Group II (Roll-formed steel shapes).6.2.4 Polymer-coat

The color shallmatch the system in accordance with Specification F934.6.4 Fittings6.4.1 The nuts and threaded portions of fasteners used tosecure welded wire mesh panels to the framework must eitherbe inaccessible from the attack side of the fence structure withthe thre
28、ads peened, or, if exposed, must be tamper-proof,peened, or welded to prevent removal. Fasteners and fittingsshall be of sufficient size, strength and design to preventremoval of the fabric.6.4.2 Fittings used in securing mesh panels to the frame-work shall have a strength that closely approximates

Security, location, terrain, and other design pa-rameters must also be factored into proper installation tech-niques and fittings usage.7.2 Caution Reg
33、arding Wind LoadsFramework and con-crete post footings must be designed to withstand the expectedwind load forces.7.3 Positioning Welded Wire Panels7.3.1 When welded wire panels are installed continuouslyon the attack side of the fence they shall be firmly affixed insuch a manner that the attack sid
34、e of the post and rails are onthe same plane (to enable secure attachment of the welded wirepanels to the framework). Install the mesh panels, with thedirection of the larger horizontal mesh opening pattern of thepanel running either horizontal or vertical. When installedbetween posts, welded wire p
35、anels shall be securely fastened toboth vertical and horizontal framework members. The overlapof adjacent panels shall be securely attached using the specifiedsystems attachment method.7.3.2 Panels shall have no more than a 1-in. (25-mm) spacebetween the bottom of the mesh and grade. Backfilling sho
36、uldbe performed where appropriate. Additional security can beobtained by burying a separate section of polymer coated meshof the same gauge and mesh as the adjacent mesh a minimumof 24 in. (610 mm) below grade. Overlap the buried mesh withthe fence mesh a minimum of 6 in. (153 mm). It is recom-mende
37、d not to hog ring the two fabrics together leaving theburied mesh free to adjust to possible movement due to frost.In lieu of burying mesh, install a concrete grade beam of thewidth and depth required for security, soil conditions, and frost.7.3.3 When connecting panels to line and terminal posts,co
38、nnection points shall not exceed 15 in. (381 mm). Whenconnecting panels to horizontal rails, connection points shallnot exceed 15 in. (381 mm). For added security, mesh can beattached (sandwiched) to the terminal post using a galvanizedsteel strap having a minimum cross section of 112 in. (38 mm)by1
39、4 in. (6.4 mm) with holes spaced 12 in. (305 mm) on centerto accommodate minimum38 in. (9.5 mm) carriage bolts thatare to be bolted through the strap, the mesh, and through theterminal post.7.3.4 Exposed edges of cut welded wire panels are verysharp and should be avoided. Overlapping panels more tha
40、n thestated minimum above is the normal practice and is acceptable.7.4 Grounding to Earth: Grounding of the security fencesystems, when required, shall be in accordance with local code,and be installed by a licensed electrical contractor.7.5 Barbed Tape: Barbed tape shall be installed in accor-dance
